About the only thing close to a specialized tool for the project was a #6 roll pin punch to get the clutch/brake pedal linkage out and back into the new frame. The air ratchet speeded things up quite a bit.
Everything is pretty much swapped over up to the point of flipping the new frame over and mounting the transaxle. Note I left bolts in the old frame so I would know which ones went where. Momma didn't raise no dumbaby.
