Conversation Between firstrider and Jim 41

Hey firstrider, Jim 41 here, I'm buying a 41' ford pickup this week, it has no heat and I'd like to install a heater box, from what I've seen here on FTE your the man I need to speak with. Do you have or do you know of a 6V heater box that is available for my application? Magic Air or Ford ? Any good box? Restored? I'd really appreciate your help on this matter, Thank's Jim41 my email: jgaf39@aol.com
