The 49 Buick I bought has a shortened, cobbled up triangulated 4 link rear suspension. It's ugly and doesn't work very well. It uses a GM 10 bolt rear with factory 4 link setup. I have been researching and trying to figure out what I can do to straighten out this mess. It seems that the late 60's-72 Chevy truck suspension might be a good direction. It doesn't look like a 4 link parallel setup will fit vey well. I have not been able to find any good pictures of the Chevy truck setup. I know that the bars are sort of triangulated inward and that it uses a pan hard bar to locate the rear laterally. How does the rear axle "pivot? I.e. How does one side go high while the other goes low without binding? Is it easy to custom fab one of these setups using tubing? Are there any pre- engineered kits available? Please post some pics showing me the business ends of these setups so that I can understand them better and/ or point me to some links. Any precautionary advice is appreciated, too. Thanks!
