Will 95 chevy leafs fit a 74 chevy?

[Barmypark]

My buddy wrecked his c20 and im buying a k1500 for parts for my two trucks so i was wondering if the leafs from my 1500 would bolt in for his 74 c20 he blew both of his rear leaf springs to bits in a drifting accident lol. If not ill probably turn the 1500 into a go kart.

Are they 63 inch springs? (I believe?) If so you need to do minor custom work, 20 gallon gas tanks on the long wheel base, single cab trucks wont work iirc, without putting axle not centered in wheel well
Also a half ton gmt 400 springs shoould NOT be used on a 74 c20.

heres a 76 c20 (actually a trailer, but its a 76 c20 nonetheless) with smaller rear brakes (11 inch) and presumably a good but not largest spring pack possible

heres a 78 k10
unless you are prepared to 1) use your truck like a halfton
2) be unbalanced to your front suspension
3) also do a LOT of work, new hangers, busings.. etc...
