Rat Patrol,
Do notice that with the combo above, it was not necessary to shave off the rear pan rail ears on the side of the block. In fact, in that pic you can see the factory reinforcement bracket bolted up to the ears which braces the lower block and transmission together.
They're all factory components, engineered to go together in a '05 Dodge Ram. That's what my original goal was, to use as many new factory parts as possible, put inside an old body shell.
