I have a '49 1/2 ton that has a Harrison heater in it. It is not the fresh air heater that goes on the passenger side. I can't find any model number on the heater, other than the Harrison logo on the front. The round core in the heater leaks and my local radiator shop told me that it couldn't be fixed because the leak was down in where the tubing enters the core. I've been looking around for a core, but before I spend too much time, I am wondering if this is the right heater for this truck to begin with?? If not, what would it have probably had in it? (this truck was from GM Canada) If the correct heater, any suggestions on how to find a core or someone who might repair one?
