They make all the stuff to get your truck running again for the heater core.One thing you need to work on you need to take the AC box off the fire wall get a new gasket kit and a new heater core and clean the outer box and inside with simple green and repaint it black.Then spend the 300-500 for all the parts to make the heater and AC unit ready to use.That peace out on the fire wall is the one i rather look at first cus if the heater core is bad it will leak and smell horrible.In my 1971 i did what i did it blows so hot I changed the controller and cables all in one motion cost me 139.00 about 4 1/2 years ago the ducking under the dash the 2 plastic peaces will cost you 115.00 the metal heater thing you can find it at any one of these guys that sell used parts plus there are 2 relays you have to change one for the AC and one is for the Blower motor that is another thing bet off changing the blower motor and clean out any crap that has collected in or around the blower motor fan wheel
