Ball joints!!
 

Here we go again. I am lost..surrounded by ball joints. Here are the numbers. Which ones are correct for my COPO. Everytime I buy parts..I need to get "other" parts instead. Help! https://www.yenko.net/ubbthreads/imag...lins/dunno.gif

3997409
3963842
9758711

Thanks

Re: Ball joints!!
 

Upper Ball Joint #3963842 was ORIGINALLY used on:
1964-72 Chevelle
1967-69 Camaro
1968-72 Nova
Also used on A-F-X bodies for B-O-P too.

It was soon discontinued and replaced later on in late 1970's with Upper Ball Joint #9758711 which was to be used on vehicles previously mentioned,plus 1973-74 Novas.

Upper Ball Joint #546174 would Later supercede it,with same Vehicle applications.

Upper Ball Joint #3997409 is 1971-72 TRUCK.

Frank Payne,formerly from Flying A Restoration in Omaha had the rivits.
He's a member here.

Make sure you have the Oval Flat top,and not the round Bubble top,to be original assembly line correct.Also,boxed NOS have the larger holes to accept the replacement service bolts,not for the rivits,as used on the line originally.

What does a person do then if you want to be 'assembly line correct'? If you use a sleeve between the rivet and the larger hole, will the rivet head be large enough to cover up the sleeve?

Re: Ball joints!!
 

You can get the rivets from a place called AMK Products.They are exact to the original ones,as I compared them to my original ones.I also got some from Flying A,they too were correct.I know someone here who can rivet them in for you, he does great work.I had him do mine off my ls6 recently. Do you need the correct 1/4" inch ones or are your holes 5/16th?

Re: Ball joints!!
 

I have a set of the #3963842 which I believe are the 1/4 inch versions. I have a AMK catalogue..I'll take a look.

K92 could you PM me the guy to rivet them.

Thanks

Rick:
Not to step on anyone's toes, but the right rivits are flat head and I've never seen anyone supply the right ones. I'll attach a few photos.

Chevrolet used flat head rivits, installed from the bottom. The "oval" head you see on the top is the result of the rivit set used in riviting. I happen to have a large selection of rivits, so it is not a problem for me to make them right. In NOS ball joints with the large 5/16" hole, I use a 5/16" (as opposed to the orig 1/4") flat head rivit and turn the flat head down to the OD of the 1/4" rivit's head on a lathe. I made a rivit set and hot bucked them in place - it helps to have an extra set of hands here.

Note that the "oval" head in the photos is irregular - not at all like an oval head rivit. That irregularity is a result of the rivit set (the tool that forms the head).

You just can't make 'em look right with the wrong rivits!
