I've been looking everywhere for new gaskets/seals for my 79 ac heater box. Any help would be greatly appreciated

They are not something you can buy. Mixture of sponge and rubber as required for heater box, black cork tacky tape/aircon dum dum sealant for outer case.

I had restored a couple of these under the dash boxes, and what I had done to replace the foam type seals was simply buy 6mm thick soft cell foam for a few bucks from a foam and rubber store, some very thin 3M double sided tape and use the old busted foam to cut the new one to size and it worked perfectly well.
