Spiral Shocks
 

I am trying to find what these original Delco spiral rear shocks go to. One is #3192453 dated 202-68. The other is #4975155 dated 350 72. Any help would be appriciated.
Thanks.

Re: Spiral Shocks
 

The #3192453 is a rear spiral shock for the 1969-70 Impala-Biscayne-Bel Air-Caprice series,but NOT with a 427 or 454cid or Heavy duty Suspension or Super Sport or Taxi or Station Wagons or Air boosters or Heavy Duty chassis..i.e.Budd Frame.

The #4975155 is a L/H rear spiral shock for a 1973-74 Chevelle series,but NOT Station Wagons or El Caminos.

Thanks very much mr70. I've had them laying around for 14 years I think I'll sell them.

Rick, Did you write the book for Chevy? https://www.yenko.net/ubbthreads/imag...iggthumpup.gif https://www.yenko.net/ubbthreads/imag...lins/beers.gif

No but he must have every damn catalog/manual/piece of paper that Chevrolet printed !!

Re: Spiral Shocks
 

Not to hijack this post, but one of the posts above insinuates that Budd frames were heavy duty - From all of my research, I was under the impression that the three frame suppliers: A.O. Smith, Flint Frames and Budd, supplied the same type of frame. They were all the same. Can anybody comment on this? If Budd did make a heavier duty frame, what was different about it?

Thanks

Hi Rob:
I will let the experts comment but I have never seen any major differences.It seemed the manufacturer of your frame was determined based on the location of where your car was built. I have taken Budd frames out of 6 cylinder cars and we have two in our 427 cars.Have to love the SO cal ones.

That's how I understood it too. Jon Krogh also told me the same thing... And he has taken apart scores of cars. You never know though... https://www.yenko.net/ubbthreads/imag...lins/smile.gif

That's my personal "i.e." reference after Heavy Duty that I believe Chevrolet really used in that situation back then.
Of the few heavy duty suspensions I have seen in person on any GM B-body,Buick-Olds-Pontiac-Chevrolet,all have had Budd frames.
I can't find it right now,but somewhere I have a internal product bulletin stating Chevrolet preferred to use that manufacturers frames when special heavy duty suspensions were requested before assembly.
It when on to say because Budd used a heavier gauge steel on it's one piece tunnel bottom & welded on channel rails then other similar frame manufacturers at that time,GM preferred to use them more in case of warranty issues.
I think Parish Pressed Steel later on adapted to this design as well..

Hi Rick:
Be careful now you are crossing into that B body dark side. https://www.yenko.net/ubbthreads/imag...lins/blush.gif If you say there was a letter there was just that it does not seem GM followed it on B body.They increased frame guage in 1966 for sure after having warranty issues in 65 this was enforced by all frame manufacturers.I have 6 frames right now as samples all BB cars, 5 of 6 were 4 piston disc brake cars and all had heavy duty suspension two with F41.
In this mix 4 Budd and 2 AO. I have blasted one of each and and seen no difference in welds nothing.The boys talked about this some also on the impala site. Would be interesting to prove.

If I remember correctly, in '67 they went to a full boxed frame vs. the open 'C' channel that they used in '66 or '65. Full boxed under the rocker panel that is...
