Any recommendations on where to get/not get a new heater core and AC evaporator? Any of the aftermarket ones any good, or run OE only? If so, what's the Mopar PN? 93 W350.

Are evap issues common on these rigs?

I'm tearing the dash apart pretty far to swap cab wiring harness for my cummins swap and the heater core was starting to weep IIRC so figured I may as well replace it. Don't recall any AC issues, but if I'm going in there may as well replace it if it's a known weak spot. That being said, I don't want to put junk in and have it go out.

Jim Lane had a write up covering the heater core IIRC, make sure you take your cores with you where ever you decide to buy and look closely at the tubes that the hoses connect to, a lot of them are not right even though they say the will fit our trucks.
