Yesterday was a very long, 21 hour day. Picked up my 4.10 rear yesterday morning with 80k miles on it, got back to the shop and started working on the bumper kit from Mike. Once we got part of the bumper wrapped, we had a look at the rear, pulled the cover and found a G80 stuck in it.

Any other situation, I'd been blown away to have purchased a non-G80 rear and got one, instead, but my Powertrax locker stared at me from the workbench in disappointment. For now, I'm going to ship it back and see how unreliable the G80 is for my ventures. If flaky, which I expect it to be, I'll look at getting a Detroit TrueTrak or similar since the carrier is not usable.
Got the bumper together and primered at about 2AM this morning so I can work on getting it sprayed the next free day. I still have the radiator skid to complete, but need to dig a bit more to figure out what's going on with the bolt that goes to the frame on the skid support, behind the radiator support. My frame doesn't have a hole for the bolt, so I'm probably just missing something.
