Ok, did the tranny swap.

Couple of issues, the parking brake is totally different and the rear prop shaft has to be shortened by 3.125"

Pulled the shifter, removed PTO shaft, removed front of prop shaft, removed transmission. You DO NOT have to remove bell housing to remove transmission. You CAN get to the two bolts that go into the trans from the front. Remove inspection cover and they are right there!

I have a 5.57:1 T170 axle, tore it down also. Found a Detroit "no spin" for this axle on ebay!
