8.8 swap
FWIW, I had really good luck finding our 8.8 on craigslist. We paid $120 for an 8.8 3.73 trak lok explorer rear with new rotors and pads. Than I went to a local pull your part, and picked up a second short side axle for $24 along with the C clip. I just need to go back and try to get the drive shaft adapter for the pinion yolk.
From calling around locally its going to cost around $150 to have the long side of the housing shortened to match the short side.
Hope this pricing outline helps. Eric L
