Dave Those look really thick and stiff.
Let me try the 71 springs I have or I have some stiffer overload springs off my other 71 shortbox. I want to keep the truck at the same height it is now, Just do not want the springs banging together at the coils like it does now. Yes I need the tight radius at each end for the hold-down bracket.
Sorry the cruise was lame. I worked on the new brake lines today then went to the junkyard this afternoon but they closed early today and would not let me in.
Put in longer wheel studs in both rear axles. the old studs only caught about 4 threads with these thick aluminum wheels
