It's been a long time since we've been here. But we're re-starting our build (again) I need some advice on rear coil springs and what donor springs I might be able to use.I'm building a C.R. with a 351 windsor. I have a Ford 8.8 rear end. I bought a partial kit from someone ages ago and the springs that I have are too short. They are 3.5" inside diameter which seems right but they are not long enough. ANYBODY?????
