Both of my sno-cats have Mopar heaters similar to that, but not identical. They use hose (1-3/4" I think) from the two outlets to the nozzles on the dash, which in the case of the Tucker were custom Tucker nozzles since the whole cab is their design and is all aluminum. The hose is an odd-ball size these days, but House of Hose in Spokane had some. The neat thing about the newer models of those MoPar heaters is that there are two fans inside them. There's a regular fan that blows a large volume of air at low pressure for cab heat, and on the same motor shaft there's a large squirrel-cage blower that provides more pressure for the defroster. The '56 has the newer version, and the '52 has the older one that just has an ordinary fan. That one also has the dangerous feature of having the fan mounted in the open behind the heater box so if one reaches around behind it while the fan it on, it bites your fingers, as I learned the hard way.
