"G" Body suspention tips ?

[Brian Fink]

You need to start fresh with coil springs both front and rear ( Moroso will work ). Shocks need to be race specific and in this case a call to Calvert should give you what you need . Any of the major control arm companies will also get you in the ballpark along with a one degree pinion angle ( to start ). Also, as Alf Wiebe will tell you , use a rear sway bar !

sounds like binding of upper control arms. stock uppers and old 12 bolts cause binding due to angularity differences. need the uppers changed to rid yourself of this problem to start.

I guess the question is, is the 12 bolt modified to fit the G-body? Are the upper ears located in the proper angle to the upper control arms? If it was an "A" body 12 bolt, the upper control arm attachments are not in the proper location. You probably can force the control arms to fit but it will seriously bind. Post a little more info on the 12 bolt install.

They make the control arms to put the "A" body rear in the "G" body, with the correct angles.
Can't remember who, maybe the "Iceman", I think there's a product line under that name, think he even sold/sells on Ebay.

There was also a 12 Bolt made for the G-body. Oldsmobile had it done and was given out to the factory cars. Just like the non computer q-jet & Dist. There were parts from Canada.

Most of the major chassis shop's such as Strange, Moser, Mark Williams make a complete bolt in 12 bolt g body car.

The upper ears on the 12 bolt are way lower then the ears on the 7.5" I had. With the stock upper control arms the one on the right seemed to fit alot better then the one on the left. do you think putting in adjustable upper control arms will be enough or do i have to get the ears on the 12 bolt raised. or do you know of any kit to raise the upper ears ?

Thanks for your help,

When you raise the rear up on those cars for tire clearance, the projected instant center goes out of this world.
Do a search for no hops bars. Several companies offer them. Get the proper upper control arms. I'll have to assume that you've got the wrong lower ones,too.
Don't forget some good shocks and air lift bags.
That'll stop the bouncing.
