1973-1977 GM A-Body Roll Axis
I’m building a Pro-Touring 1977 Pontiac Lemans (CanAm) and inherent in the build is a “stealth” cage and frame boxing. Generally the 73-77 platform is said to have the best suspension geometry(versus 64-72 & G-bodies) but thought someone may have the key suspension data so we can determine if the 4-link is replaced with a 3-link(rear roll axis is way too high on other A-body platforms) and the front end needs additional geometry changes since the roll axis is way low(AFX spindles, taller ball joints) in addition to the Global West Coilover control arms.
it’s being built by Mike DuSold so we can spend 8 hours calculating the geometry but if someone already has the data that they will share; it would be much appreciated.
Thanks,
Randy Allen
