During this time frame, my power plant wishes changed, so I bought a Duramax/Allison combo, but it was a super tight fit, and I did not want a body lift. I sold it and found a L92/6l80E combo out of a Hummer H2 with 13K miles on it:

I had purchased the DIY4X engine cross member for the small block I had, but it was not going to work with the LS engine:

So a quick slice and the engine settled into place:

Tight fit:

As far back to the firewall as I wanted it:

I bought a 1990 NP241 passenger drop transfer case and changed the input shaft to a 32 spline to match the 6L80 and installed a slip yoke eliminator kit (no pics for some reason)

Transmission/transfer in location for cross member:
