UCA & LCA Suspension input needed

[Mr. Greg]

Hello,

I'm working on a non-standard build, I am using a 5th gen G-body frame under a 1941 Chevy Coupe. The frame fits nicely under the car as the wheel base is with in a inch of the original length (excluding the frame rail ends, which get chopped off). Currently, I have the ride height set at where I would like it to be, which is low. I want to going to go with coil-over's instead of airbags. Once I set the ride height, I'm not interested in really changing it. I do plan going with a tubular UCA & LCA, but I have to figure out how to correct my positive camber issue, and looking for a shorter UCA.

I have read a lot of forums about swapping suspension parts between A, B, and maybe F Body cars. My primary question, is there any source that compares the differences between the LCA & UCA's from the A, B, G, F body makes? Mainly lengths (as it sounds like the mounting points are the same)? And which spindles are the shortest?

Thanks for any input.

G body uppers are offset 1 1/4". The F body uppers are equal length. The B body uppers are longer than the G body uppers. UMI has tubular uppers and perhaps they could made a custom set for the length you need. UB machine makes different length upper control arms but they are very hard to deal with.

Here are some rule of thumb stock measurements:

G-Body - 11 1/8 upper, 19 1/4 lower, If you use rod ends or roto-joints on the adjustable lower you can be from 18 3/8" to 20 1/4" range

F-Body - 19 1/4" lower

A-Body - 1964-1967- 12 15/16" upper
1968-1972- 10 1/4" upper
22" Lower

B-Body - 11 1/4" upper
22" lower

Mustang - 17 5/8" lower

If you need something give me a call, we might be able to help you out with what you need.

Thanks both for your input!

I am working on tying in custom body mount brackets to use the factory body bushing points on the frame. Once I get the body bolted down to the frame and know exactly where its sitting, I will send you a private message Craig. I am definitely interested in some help, so I get it right.
