63\" 88+ 1/2ton rear spring center pin location?? I am going to the junkyard tomorrow to get a bunch of stuff for pretty cheap. I want to look for 57" ford springs but I know there is a like 90 1/2 ton sitting there that I can get the springs from for like $40. I'd like to keep her all Chevy anyway /forums/images/graemlins/thumb.gif. Anyone know the center pin location on the 63s? I know I will have to move the rear shackle mount back on the frame as well as shackle flip it and longer shackle. I know at least one person has done it here and was happy.
