There are companies that make bellhousings/sell them, but they are all from australia and shipping would kill. They are extremely reliable, simple wiring, only takes bout 5 wires to run I've heard. Suprarunner off pirate4x4 can get you everything you need besides the wiring aspect, motor mounts, custom welded bellhousing, clutch and flywheel... Im planning one for my truck.  


Its the same block pretty much as the 4.7 tundra(2UZ), except the 4.7 wont except an input shaft from a manual trans.
