I said it had been thru some changes.

The Dana 60 rear was fine with a small block. I decided I needed MORE POWER. So I built a 496. 550 lb.ft. of torque is awesome! Until you put on some new mudders and step on the right pedal. It will shear the axle flange right off the end of the shaft. When my wife asked "how did you do that" the only reply I could think of was "stepping on the gas".

That required a new axle or 2. Come to find out the 70's and 80's military GMC pickups (M1008 I think) have 14 bolt rears and Dana 60 fronts that bolt in with only changing the rear shock mounts. They come with 4:56 gears with a Detroit Locker in the rear and a posi in the front.
