so my blazer broke the pinion gear on the 12 bolt rear end, its going to be alot of money to fix it and resulting damage so i figure it will be cheeper to get a new rear axle and put it on myself. i hear from theese threads its pretty easy to find a 14 bolt for around 200 dollars, but i dont plan on going much bigger than the 35's i have, maybe 37's in a year or so. i need a solution as soon as possible, so any vendors with good deals or people trying to sell what i need i will buy it as soon as posible. so the question is, 1. does any one have a 12 bolt rear end with 4.10's or 4.56 in the northern colorado area for around $200 or less 2.do i need new spider gears and what not, or can i just get a new ring and pinion and a locker. 3. any ideas on where to go to get it fixed in fort collins/loveland cheap, and any other ideas would be apreciated.
