Thanks for all the info. I just called my wrecking yard and he says he has plenty of chevy trucks, just doesn't know any length on the springs. When you say 56" springs, are you measuring from center hole to hole at each end?? Here is the other problem, they are all still on the trucks, so they have a load on them. Is there another way to get what I need, like what year truck are they common on?
