Grumpy, there has to be a place local to you with all the hot rods up there near the motor city. I'll bet if you called a few transmission shops, you could find someone to build you a big 2004R out of a decent core. I'll bet Jake of Jake's Performance could at least give you a parts list and point you towards a builder.
