For many years auto parts stores offered fit all heaters for sale.They had names like Southwind and Hades and many more.J.C.Whitney and Western Auto were a couple of the retailers.Auto parts stores may still have them for sale.The heaters were nothing more than a box with a heater core and a fan and motor.Also they had a couple of fold open vents and a couple of outlets for windshield defroster hoses.Why not just make your own.You only need a few tools like a drill,a screwdriver or two.Sheetmetal shears and a Poprivit tool.Go to your local wrecking yard and pick up a heater core and motor with fan.You should be able to make something in a couple of hours.Anybody can buy something,but if you build it,you have something to be proud of.
