70 Chevelle sport steering wheel
 

Does anyone have any info on any 70 Chevelle having a 16 inch sport wheel with the thumb groove as seen on the Buick Grand Sports installed at GM? I went and looked at a 70 L89 car today and it had this wheel on it. Car was built 1st week of September.

Re: 70 Chevelle sport steering wheel
 

I have only seen 16" Buick sport wheels on the later Buicks. I have never seen one on a Chevelle.

Re: 70 Chevelle sport steering wheel
 

Did it have a small recess running around the inner edge, facing the driver?
Fuzzy picture, but this one has the recess I mentioned.

Hey Rick that's the one.

Re: 70 Chevelle sport steering wheel
 

It's my understanding that this is THE correct wheel for the `70 with NK1 option. The one that everyone puts on to replace their cracked one is usually designed for the Corvette.

Got any pics of the wheel on the one you went to see. Hey how about some info about it's L89 status!!!

Re: 70 Chevelle sport steering wheel
 

Are you guys saying that THIS ISN'T the correct wheel for the 70 Chevelle, but are saying that the Buick THUMB GROVE wheel IS correct??? I thought the 16" Thumb Grove wheel was only used on the 69-70 Buick GS.

Ed

Re: 70 Chevelle sport steering wheel
 

I'm just saying that it MAY be correct for both the Buick and Chevelle in 1970, but I'm not positive.
I was told years ago that this is the correct NK1 option wheel for the Chevelle. I never researched the Buicks to know if they were the same or not.
My `70 LS5 car is supposed to have the NK1 as listed on the buildsheet, so I'd like to get some others input on this.

Re: 70 Chevelle sport steering wheel
 

Well, here's what I've dug up so far on this steering wheel from the sources I have:

* P/N 9752131 comes up as 1970 Chevelle & Monte Carlo, and 1971 Full size passenger car, Chevelle, Nova and Camaro "Three spoke cushion rim steering wheel". This part number is listed in the 1971 P&A 26 (Price Schedule) as being used only in Chevrolet models. No Buick usage.

I need to verify the 1970 application though, since I don't have a 1970 P&A.

* The 1970 usage above came from an article written many years ago by Ken Moorehead and the 1971 usage came from the 1971 P&A 30M (attached).

If anyone has a P&A for 1970 showing this wheel, can you please elaborate??

What I'm confused about is the Price Schedule stating this wheel was only used in Chevrolet models. If the Black "Thumb Grove" steering wheel really IS P/N 9752131, and it was used on the 1970-1971 Chevelle AND the 1969-1970 Buick GS, the Price Schedule would reflect this.

Re: 70 Chevelle sport steering wheel
 

Note (2) in the attachment says the sports wheel is 4-spoke!?!?

Re: 70 Chevelle sport steering wheel
 

Yeah, that's THIS GUY.

Ed

Re: 70 Chevelle sport steering wheel
 

Here's a thumbnail scan from my parts book, sorry it's crooked. Shows part #9752131, but this is a 1975 book.

Now we need a Buick parts book to compare.

Re: 70 Chevelle sport steering wheel
 

Thanks Rick. So from that we can also add 1972 to the list! The picture doesn't show 1973-1975. Does that P/N apply to these years as well?

Finding someone with a Buick book is going to be next to impossible!!

Ed

Re: 70 Chevelle sport steering wheel
 

That big 16" wheel is a 1969 Buick piece. It was never used by Chevrolet and was not even used by Buick after 69. I'd be willing to bet on it.

Re: 70 Chevelle sport steering wheel
 

I'm hoping you're right Joe. I really don't want to have to modify the Camaro Steering Wheel report now that I'm done!!

I've asked over on the Team Buick site if anyone has the Buick P&A so they can look up the P/N for us.

Ed

Re: 70 Chevelle sport steering wheel
 

From what I know, the 15" rubber 3 spoke wheel came out late in 69 and was offered as an option on Camaros...as seen in the thread in another forum with Lillard's RS/SS. (see window sticker and photos of interior) It was used in 69-74 on Corvette, and in 70 in Chevelles, and was made in a bunch of colors for Buicks. Chevelle SS always used black only, as did Corvette, regarless of interior color. The 4 spoke rubber wheel was never used in a 70 Chevelle, nor was the larger 16" '69 Buick 3 spoke wheel. Bottom line, the only 2 steering wheels you could get in a 70 Chevelle SS was the 2 spoke standard plastic wheel, or the 15" 3 spoke wheel in black.

Re: 70 Chevelle sport steering wheel
 

My parts book from September '75 lists
333590 - 1970/All - used as cushion grip steering wheel / SUP 3952700
9752131 - 1970/All - used as vinyl steering wheel - only available in black
9752131 - 1971/ vinyl wheel
3978125 - 1971/ 4 spoke sport steering wheel
1972 is listed the same as 1971.
My Buick book is from May 1981 and the 1969 part number is listed as 333590 with no SUP #. The same as the 3 spoke on Skyhawk, etc, from the late 70's.

Re: 70 Chevelle sport steering wheel
 

That's interesting Brad. So according to the P&A, 333590 superceeded the 3952700 wheel (which happens to be the 1969 Camaro NK1 and the 1969-1975 Corvette wheel).

It was also used on the 69 Buick, but does it say which model?? That can't be for the GS since the GS used the "Thumb Grove" wheel. As a matter of fact, there's a 333590 WHEEL on ebay right now, and it's clearly not a "Thumb Grove".

So what's the 9752131??

Ed

Re: 70 Chevelle sport steering wheel
 

Sorry, my post must have been misleading. The 333590 (3 spoke cushion grip) is the newer of the steering wheels. It replaced the 3952700 ( 3 spoke cushion grip). I have no doubt that the 16" wheel with the thumb recess is the 69 Buick wheel but does anyone know what the diameter is on the 3952700 wheel listed in the Chevelle book?
The 9752131 must refer to the black 2 bar vinyl wheel because there is a P/N for the 2 bar black plastic wheel as well.

Re: 70 Chevelle sport steering wheel
 

My 1975 Corvette P&A shows the 3952700 wheel as "69-75 Corvette, 15 inch black wheel".

My 1982 Corvette P&A shows the 333590 as "69-75 Corvette, 15 inch wheel".

Since the 333590 superceeded the 3952700, they would both be 15" in diameter.

We seem to have that one nailed down, but I'm still wondering about the 9752131 wheel. Ken lists that one in his article as 1970 Chevelle/Monte Carlo 16" (see attached). Since we know the "Thumb Grove" wheel was 16" in diameter, I'm wondering if the 9752131 is the "Thumb Grove" wheel??? <u>EDIT:</u> Nope. It can't be the "Thumb Grove" wheel since the P&amp;A 26 doesn't list it for Buick in the Vehicle usage section. Back to square one on the 9752131 wheel!

Ed

Re: 70 Chevelle sport steering wheel
 

9752131 is also listed for 70-72 Full size and Nova, all vinyl, black

Re: 70 Chevelle sport steering wheel
 

#3952700 shows up in the Chevrolet 1970 P&amp;A 30M,dated Sept.1st,1969,for all 1970 cars with madrid grain cushioned rim black steering wheel.
I've only seen one 1970 Chevelle with the 16" thumb groove,and the owner admitted he mis-installed it himself.
I too have always considered that wheel a Buick application only and have sold them more eagerly to Buick owners,as no Chevrolets wanted it..

Re: 70 Chevelle sport steering wheel
 

I guess the consensus is that the 16" thumbgroove wheel is Buick only.
Time to put mine up on Ebay.

Re: 70 Chevelle sport steering wheel
 

So then what the heck is the difference between the 3952700/333590 wheel and the 9752131 wheel (other than the size)??

I can't belive GM would have two cushioned rim steering wheels in production at the same time for the same models.

Ed

Re: 70 Chevelle sport steering wheel
 

I have no idea what they are calling 9752131 in those part books, because the same number is listed as a vinyl wheel for 1970, 71, and 72 three separate times, and I know there was NO steering wheel that was offered all 3 of those years in any chevy passenger cars, the standard steering wheels were different, and so were the optional ones. Only thing that may have been the same was a pickup truck wheel. Think about it! Do you know of any other Chevy steering wheels that were used from 70-72? I sure don't.

Re: 70 Chevelle sport steering wheel
 

9752131 is not listed in the truck parts book.
The Chevelle Restoration Guide makes note of the 9752131 wheel.
quote "Two optional steering wheels were available. Deluxe vinyl steering wheel was RPO NK2. The wheel was listed as part number 9752131, and the shroud as part number 3992587. No SS emblem was used with this wheel." end quote
I am not sure why the Sept '75 parts book lists this wheel for 1970 but what can I say? https://www.yenko.net/ubbthreads/imag...lins/dunno.gif

Re: 70 Chevelle sport steering wheel
 

That answers the question Brad. If the book says it had a shroud, then it CAN'T be a 3 spoke wheel.

Thanks for all your help guys. I really appreciate it.

Ed

Re: 70 Chevelle sport steering wheel
 

FYI, that Chevelle restoration book you refer to is widely known to be filled with various tidbits of misinformation. I dont care what any book says, im confident there were TWO (and ONLY 2) steering wheel styles offered in a 70 chevelle. The standard wheel, or the optional 15" 3 Spoke wheel.

Re: 70 Chevelle sport steering wheel
 

There was a 2 spoke rubber wheel offered as an option in 71 ( and maybe 72 too) that is likely what that 1975 parts book is referring to. It's a fairly obscure wheel and I don't have one to post a photo of, but I'll bet it has that 131 part number you are concerned about... It wasn't offered in 70, but was probably just incorrectly listed in that 75 parts book.

Believe me. I was hesitant to post that as I know of the mis-information issues. The reference quoted only refers to the wheel being used in 1971 and 1972, not 1970.

Re: 70 Chevelle sport steering wheel
 

Well, I think I'm going stick with my original perception in that the only three spoke wheel offered in 1970 was the 15" wheel as used on the 69-75 Vette. I can't find any proof (so far) that the 16" Thumb Grove wheel was used on anything other than the 69-70 Buick GS.

Everyone agree? (If not, let us know...)

Ed

Re: 70 Chevelle sport steering wheel
 

I'd agree with that.
And I believe many pages from Herds restoration book could've helped Les Quam in Colin's bathroom,and I don't mean for reading..
I know someone who has had a 9752131 wheel,but I only have an old email address from years ago and have emailed him 2x since this post started to see if he can email me pix of it,or at least a verbal description.
His email hasn't bounced back,so fingers crossed.

Re: 70 Chevelle sport steering wheel
 

There was a 71 "heavy chevy" claiming to be a pilot car advertised for sale a couple years ago that had this wheel. I saw the car at Carlisle, and recall seeing it advertised online too... Anyone recall the car or maybe know how to track down a pic?

Re: 70 Chevelle sport steering wheel
 

Let's hope for the best Rick!! Keep us posted...

Re: 70 Chevelle sport steering wheel
 

OK, I've been doing some digging, and I found a pic of what I believe is the "mystery" 9752131 steering wheel. This one is in a Monte, but I believe it was an optional wheel in 71 and 72 for Chevelle as well...I know the "Pilot" 1971 Heavy Chevy I was referring to in a previous post had this wheel in it, and was supposedly documented on the build sheet as being the original "optional" steering wheel for that car. Definitely a pretty oddball piece. Ever see one?

Re: 70 Chevelle sport steering wheel
 

After some MORE digging... here's the original build sheet for the 71 "pilot" Heavy Chevy... Note the NK2 steering wheel option.

Re: 70 Chevelle sport steering wheel
 

I agree,that's the same wheel my friend had before he sold it.
To summarize for Chevrolet:
*1970 RPO NK-1 is the optional Cushioned Rim madrid grained vinyl 3 spoke 15" steering wheel,part #3952700.(larger 16" thumb groove is the Buick application)
*1971-72 RPO NK-2 is the optional Deluxe Custom madrid grained vinyl cushioned center &amp; rim steering wheel,part #9752131.(Cjoe pic above)
*1971-72 RPO NK-4 is the optional Sport madrid grained rubber coated 4 spoke steering wheel w/simulated stitch,part #3978125.(pic below)

Re: 70 Chevelle sport steering wheel
 

I agree with that.
