I have searched most vendors but I can't find a foam seal replacement set. I might be using the wrong terms or maybe they don't make a kit.
I hope someone knows where to get them.
Thanks

 

I just made mine out a sheet of 1/4'' foam with an adhesive back

 

I don't believe kits are available so here's what I did when I rebuilt my heater box. The most helpful references to me were:

Trent's Heater page on North Country Specialties.

Mike Rowand's 1979FordF100 AC page.


The foam on the doors was shot so I went to Jo-Ann Fabrics and Crafts and found a few sheets of black 2mm foam.


I used the 2mm foam on the door closest to the heater core. I also used the 2mm foam to create a seal around the edge of the two sides of the AC/heater unit that bolts together on the passenger side of the cab.



For the door inside the passenger compartment area, I got a roll of camper seal from Home Depot. I like the thickness of that better than the 2mm foam.



Here is how it looked with the first piece on.


I used the non-stick paper that separated the layers of camper seal as a template to help me know exactly how to cut the next piece.


I would score the foam with a razor blade and cut it with a pair of scissors. This is what it looked like once I got the first side completed.



I had some screening material on hand so I cut a piece to fit the fresh air vent inlet and epoxyed it into place, as I found here.

This was the end result, along with the camper seal.


It might look better with either black camper seal or something similar that is one large piece. (maybe you can find a spray paint that works with it?)

 

Thanks guy's
I kind of thought I would have to make my own. I'll start looking around for the foam
