89 GMC Cummins conversion

[COS399]

Here is my 1989 GMC CC SRW 4x4 build. It had a 6.2 liter diesel and a TH400 transmission. I am putting in a 24 Valve Cummins and a 4L80 transmission. Over the last two weeks I have managed to pull the old running gear and put in the new running gear. One unexpected hurdle I ran into was that the NP205 transfer case would not bolt up to the 4L80 due to the longer transmission pan making contact with the transfer case. I had to order an adapter that spaced them a little over 1/2" apart. Just to be safe I also grinded a bit on both the transmission and transfer case just to give it a little extra room.

I ordered a 6" lift kit to ensure that the new crossmember did not contact the front differential and was surprised when it increased the ride height by 7" in the front and 7 1/2" in the rear. I was told it would settle a bit once I get a few miles on it.

Here are a few pictures for now.
