OK I want to throw my .02 in. Earlier in the thread you were considering a "big Body" like 1976 Pontiac, I guess this would be a GM B Body car (1971-1976) I have never been underneath one but I did some research looking for diagrams or photos of rear suspension but came up empty. I did come across aftermarket parts though for these cars which include Control arms which tells me they are coil spring cars not much different than the 65-70 B Body gm car like my Impala.

If I am wrong here then skip the rest.

These are different from A Body cars which some guys have been showing you for rear suspension upgrades. The first difference is the coil springs perch between the lower control arm and frame, not on axle tube like A Body rears. The upper control ares are a straight forward shot, not angled like A Body cars. Some early B Bodies like my 65 came as a "3 link" rear suspension, 2 lowers only 1 upper bar. Hi-Performance did have 4 links like I have in the 65 Impala stocker I am building. No-Hop bars are not available for these cars .I have Southside Machine lower control arm traction bar which is basically a Square tube solid bushing bar with a adjustment that lowers the attachment point on the axle effectively changing the instant center of the car which aids in planting tires. The same effect is done with the "No-Hop" bars on the A Body cars. With adjustable Upper control arms, no air bags thats all I needed to do. Not really complicated. The only heads-up is where the upper bars attach to the crossmember on frame needs to be strengthen. I would leave at 6300+ RPM with a stick at 4095 lbs. Check out my Build in this forum,
"BBC Impala update" or something like that.

I would crawl under the cars to take pics but lots of snow , blizzard outside now!
