A/C heater box

Will a A/C heater box from a 72 Satillite fit a 74 Charger? Is 80 bucks from a junk yard too much?

yes is the same... I don't think is expensive at all if is in good conditions and not just the box, but full assembly

Thanks Nacho. All I need is the fiberglass box. Tried to repair it but it was too far gone.

Don't forget to change the damper door foam seals. Won't cool worth poop after a bit of running the A/C if you don't. Heater valves are designed with a bit of "leakage" to keep coolant in the core fresh and allow for air to bleed out. Check that all damper door motors are also working correctly too.

Just hard knocks talking here. co t mean to say you didn't plan on doing it.

Finally, make sure you get some good sealant into the drip plan seam at the bottom and that the drain is clear.

Plan to buy the DMT kit to replace all the gaskets etc. Thanks for the heads up on the drain.

I used the same kind of sealant used on plumbing, something like a sticky grayshy strip ( which I think is the used originally ) similar to the windshield sealant ribbon to seal the bottom seam of the A/C box
