I know this should be posted in the 4X4 section but I figure I will get faster response here.....I have a Stock K10 72'....what type of rear is in it? and what can I put back there that will be a drop in with no mods?? the rear that is in there is a 12 bolt....Thanks.....Paul

Newer rears will work but I'm afraid you'd have to move the spring perches. 73-up rears are all over the place here. I believe several here have gone to 3/4 ton so they may have some 12 bolts laying around. I would go to the parts board and look around or ask if anyone has what u have.
