I went to look at a S/H CA18DET, it was originally a FWD, converted to RWD. Bolted to the back, was a manual gearbox, that the owner is not sure what it is....It was fitted in a 1200 ute.

Here is the info...It bolts right up to the back of the CA, it has integral bellhousing, the case doesn't look like it has been split, i.e. front and rear housings look original, as evidenced by the factory grey sealer....Had no shifter, but it has a "single rail" shifter rod, and on top of the shifter hole, about one inch up, it had a thick pin running across the shifter hole, it looks like the shifter, would pivot on this pin. So what do you guys think it is ? Your answer will determine whether I buy the whole lot, or just the motor....
