I am starting my Blazer Chalet project. I have owned a '77 K5 for some time and I bought a Chalet from a junkyard about 5 years ago. Right now I am starting from the ground up so I have a question about the 12 bolt axel. The axel is original and untouched with 3.08 gears. It will need a complete rebuild with 4.11 gears, LS diff, outer bearings, and possibly axles. I am also going to install rear disk brakes. The question is will this axel be ok to build or should I get a 14 bolt to build up? I have 32” BFGs and being a camper it wont see any hard off road use but I will see some. I am going to rebuild the front Dana 44 so one down side is the 8-lug wheel the 14 bolt has. I like my wheels and I do not want to buy different ones. I want to use the 12 bolt so guess my real question is this axel good enough to use under the Chalet? Thanks for the input.
