You pretty much have two routes you can go.. There's an Advanced Adapters rear output shaft that can be swapped in the transmission, but this requires a complete tear down. You can also get an adapter plate that goes in between the trans and transfer case... works with the stock output shaft but this adds even more to the overall length of the assembly. The advantage with the plate is that you get much better clearance at the front driveshaft. With the AA shaft, it's really close and I doubt you could ever get a deep tranny pan in there without major modification.

I used the AA shaft and (following BobbyK's advice) moved the engine forward 1 3/4". If I were to do it again, I might think about using the plate adapter instead and then moving both the engine forward and the cross member (transfer case) back. I think the engine is about as far forward as I would want to go at this point.

Sorry I can't find a link to the plate manufacturer.. it was in Texas. I think I remember it being referenced on this board though.

Also, you'll want to look for a 'K' -case 700R4... It's a beefier case used in trucks. If you look at the attached pic, you can see the 'K' on the side.
