I had a non-air cab to start with and wanted the factory "look".

I bought part of the kit offered from oldairproducts.com. It included the evap/heater core assy,wiring harnesses ,and duct hoses that will replace all of the original heater parts. The finished look is very clean. I used original duct vents/ac balls and cut the holes in the dash very carefully. the compressor is a A-6 long style w/custom fit hoses using all the original alum. end fittings. I had them put service ports for r-12 and 134-a freon so if the r-12 gets impossible to find later down the road I can switch easily.

If i remember correctly I did the install in a weekend w/a case of beer....and it still works like a champ 6 years later
