I still have a PTO unit from the NAPCO stuff I sold a while ago. I was
told it was a 2-spd/rev PTO and is still mounted to the truck 4-spd; came
off a 55-59 GMC 1-ton NAPCO. Buyer didn't want the PTO because it was a
rear take-off and there was water in the transmission!; don't know if it
could be adapted to the front or mounted on the transfer case. Anyway,
E-mail me off list if interested...
