Sorry Mudbug, can't pm you back, in answer to your question, my truck is a 77 k5, but you can use the spring hanger off just about any truck that uses rear leaf springs. I personally used 'em off an 82 1 ton, gave me almost 6 inches total, plus went from 6 inch blocks to 2 inch to give 8 total and a nice comfy ride. You can even use ones from a f*rd or d*dge, though the line up may be different. I also picked up 2 used sets of 4 inch front springs and mixed and matched leaves to build one good set, fabbed up some longer front shackles, and scrounged pinion shims from a broken set of rear lift springs for 8 inches up front. Got right at 92 dollars in my entire lift and wheel the crap out of it.
