Talked to Mike @ ORS and his harness is wired to use the 3.0 AC amp, so that's a relief. There was a mistake with his harness for the auto OD button and he's going to help me with that.

Got the wideband A/F sensor installed beside the front O2 sensor:

I made a copper heat sink for it because the instructions said it was nessesary if the wide band probe threads got up to 900 deg F. My EGTs have been running about 1300-1400 deg F so I figure the wide band probe may be seeing 900 easy.

I found a good place to do driveline work in OKC, Blumenthal drivelines. Their shop is very clean:

Here's their welding room:

Larry, the owner has a rock crawling rig:

I got the rear shaft shorten about 8 inches and balanced for about $60. Here it is going on, I love that tranny jack adapter:

I have a bit of vibration with the rear shaft and after talking to Larry he said this is the problem:

The angle from the T-case to the center bearing is too extreme. So today I raised the center bearing support about 5/8 of an inch by putting the bearing on top of the bracket unstead of under it and using a spacer. That helped a lot but I may also lower the tranny just a fraction too.

I also found a good place (Auto Air of OKla.) to do the AC conversion. $170 and they said they would blow out the system, evac and recharge with oil. They seemed to be confident that would be all that was needed.
