I tried the search and for some reason it isn't working at all for me.
I'm due for a rebuild for my rear diff AMC20. What shops are you guys trusting and taking it to for new gears and locker install? I've been missing about 2 1/2 teeth on the ring gear for about 3 years and the locker is some what chewed up for about 6 years but working this winter it's time to have them all replaced. I've dealt with Modern for about 40 years but need another for now it seems.
