I believe the heaters themselves were the same. However, some of the parts associated with the installation were different. I have a fuel burning heater that was intended for a deuce installed in my M925A2. It was the same heater and most of the kit was the same EXCEPT for the wiring harness and the fuel lines. Those had to be lengthened because, on a deuce, they are on the driver's side, while they are mounted on the passenger's side on an M939. There were also quite a few parts that were left over that were not used on the M925A2 (canvas shifter boots...already given to N3UKA, Dave Olchak).
