been pulling and generally beating the hell out of my stock 70. Even broke an output shaft on the tranny. Rear is still original. I'm sure it will go any day now.

I'm guessing my 70 blew long ago because I blew my rear end 2 weeks ago, ordered new gears, went to put the new gears and realized there is a D60HD under my truck. Who put that there? 
Time for a D80.
