I have an old 72 Olds that I bought for the 455 engine,rebuilt the engine and never have gotten around to putting it in a 55 GMC like I had planned. I kept the Olds because the suspension would lend itself well to replace the coil spring with an air bag. I have a 75 Cad with a 500 that I had plans for the same thing. It think its rear suspension would work well in a pickup too.
