Anyone swap HVAC unit from donor?

LOL I cannot imagine shoehorning a ram unit "in there." BUT IF YOU DO use late model Dodge stuff, just go ahead and replace both cores.........because they leak. The first junk Dakota I drove for a short time-----AC and heater leak........The white junker I still drive...........heater and AC leak...........The white whale 1/2T I sold...........heater leak...........The white whale 3/4T I sold..........heater leak...........the Cummins I still have..........heater leak

HOW DID I FIX THEM ALL? LOLOL.........Ripped the gasket off the pressure cap!!!! ....and drove them.............
