Group and Marty, Thanks for the order and I will have new heater cores shortly. If you need any kind of rubber I have a great supplier here in Dallas that I can go over and get whatever you need if I don't already have it. Thick, thin, dense or denser open cell or closed cell. I use a non moisture absorbent barrier between the closed cell rubber foam mounted on the core and between it and the walls of the box. Try not to use anything that would or might hold moisture because of mold.

In the restoration of my car I have had everything apart for cleaning / restoration with the exception of the climate unit. Now after a lot of sweat and contortioned limbs I have it out and apart on my bench. Pulling the engine was easier(IMHO). What a mess! I had detected a small leak in the evaporator which I intended to replace. I ordered up John Hervey's kit. After the difficulty of getting the climate unit out, I ordered a NOS heater core from DMCH. (I support ALL of the vendors:) Now I am looking at a bunch of rusted flaps with no foam attached anywhere. I intend to coat all the metal parts with POR15. I am wondering what others have done to replace the foam? I was thinking about using headliner material which has a foam backing, but am unsure what the downside might be. I would install it with the clot side against the metal and the foam out. Opinions?
