Thanks for all the quick replies! It appears that I may be all set, as I can get my hands on a car engine, and it appears that I just need to get the truck bellhousing/flywheel/fork/bearing. These parts are relatively easy to come by. I am assuming that the bushing at the rear of the block is the same for both automatics and standards (I believe its called a pilot bushing). If this is the case, I'm good to go!
