HVAC box seals

HVAC box seals
I am replacing the heater core in my '98 360 magnum. I have removed the HVAC housing (aka. heater A/C housing, HVAC box, heater box, heater core box, etc.) and dismantled it. All the thin, adhesive-backed foam seals inside the box have deteriorated and or become soaked with coolant and fallen off.
Does anybody know where I can find a kit of the thin foam seals to refurbish my HVAC housing to OE spec? I have called MoparOne, O'Reilley's, and half a dozen other auto parts stores, and nobody seems to know anything, even though I have found the HVAC seal kits for newer gen Rams at MoparOne.
Please don't suggest that I go buy weatherstripping from Home Depot. Weatherstripping is made of black or gray closed-cell foam that is too dense (and too thick) for this application and will not allow the blend door to close completely among other things. I need the thin, adhesive backed, straw-colored, easily compressible open-cell foam that they used when they put it together at the factory.
Any help would be greatly appreciated.

Buy adhesive backed foam sheet (or tape) and cut to fit.
Places like hobby shops, craft shops, Amazon, eBay, packaging retailers, and industrial supply stores are the first to come to mind.
You could also try acoustical foam sheet, or upholstery foam sheet (I think you can get 1/8" with a cloth backing for strength).
There was a thread by a member here redoing his HVAV seals.

Acoustical foam supply places are likely to have a big variety of different foam sheet types and thicknesses.

Well i got mine from work, They used it to make seals/gaskets that sort of thing. They had rolls of the stuff! I would suggest looking for someone who sell it locally. If not that get a detailed info on what you will need as far as thickness size etc... and see if you can find someone on line that will sell you what you need.
