[EFI70Blazer]

My perches are actually 1 inch taller than stock, but they are welded to the housing. Basically same idea, just more effort. Springs are 4" Superlift. My 12 bolt was out of a 77 chevy, so i had to move everthing on it. I would have just found another rear end to fit my Blazer, but i already had this one. The old one that was in it had broken the welds loose from the center section making unusable. The previous owner welded it up, but was no where close to where it was supposed to be. It actually sat down in the middle 1" lower than it should have along with one of the tubes rotated more than the other. I also installed 4.10 gears and an Eaton posi while i had my new rear end all apart.
