I was wondering how long this would take. I'm building a 10 bolt cause I could never find one with 4.10 gears in it or anything close. Plus I already have this one as my spare, and the 12 bolt rear as a spare too. And another 14 bolt coming. I know I don't want to really invest this kind of money into it, but I have found no other option. It's not going to be the strongest right now, but it's not going to be built for rockcrawling anyway. maybe later I can turn it into a Bluggy (blazer-buggy) but I just want this thing geared, and then I'm going to work on my motor. I personally have found no great benefit of D44, I had them under the waggy, and they went to crap after a year. I would love to find a D60 front, but nothing yet. If anyone has a D60 geared 4.10 or close I would give some money for it and not worry about my 10 bolt. This is only running 35's right now and I don't anticipate going bigger. So I hope my 10 bolts last. Thanks for the advice though. I'll probably remember it when I'm cussing on the side of a trail.
