Long overdue update:
The 22R is sitting on a block of wood under the hood, bolted to a W56 with a 4.7 transfer case, a new Aisin clutch, and a new starter motor. The current transmission cross member is a chain, winter and life happened before I could make any more progress. On the upside, my welding skills have been improving enough that I can contemplate fabricating proper motor and transmission mounts.
The discouraging part is that my truck will probably need a new engine and transmission this year, further setting back work on the Rocky
I'm trying to have faith that it will someday move under it's own power again.
Edit: I noticed this winter that the doors do not seal against snow.
