I need a rear end for a 87 K5 blazer 6 lug with 3 : 73 gears. My local wrecking yard wanted 600 plus my rear end. There is nothing wrong with my rear end except it has 4:11s and the front has 3:73s the yoke seal is currently leaking but I was told I would be cheaper if I just got another rear end, then re gearing the front. The guy in town said he would do it but I would be looking at 400 in parts. So I am just looking to put a stock 10 bolt back under my blazer. I live in central washington.
