Got a little bit more done today. I bought the driveshaft and as I suspected it hit the rear crossmember. So that means I have to remove it and add another one further back. Only issue with that is that I have center cab mounts in the rear so I had to figure out how to deal with that. I decided to build rear cab mounts!!
I see all the S10 swaps and how they build them so, I think I can do that. Pulled the truck out of the garage, pulled the cab off, first thing......figure out where and how the cab would be secured.
