I used a jeep shaft. One tip I would give is make sure you heat the plastic that locks in the slip shaft enough that the shaft freely moves in and out. Theres enough flex between the cab and steering box to cause popping if you leave it as a tight fit to adjust the length (even with liberal lube on it). In the end, I ended up knocking all the plastic out (there isn't much of a second chance). Definately an improvement over the rag joint, and even with no plastic to take up the "slop" in the slip shaft it is still miles ahead of a rag joint.
