I was talking w/ a mechanic,and was told it's a real PITA to put a new ring and pinion in a Dana. Looks like I'm sticking w/ the 4.10s
So is a ten bolt and twelve bolt GM rear end, any non drop out rear end has to have the gears set up in the rear end housing, I bought the tools, bearing puller and pinion depth tools to do my own. I take the housing out of the car and set the new gears up in the shop so I can keep it clean, warm or cool and take my time doing it correctly. I did make some set up bearings also, which helps a bunch on setting the rear ends up
