I’m never really sure which category to put some of these questions in. Pictured is original foam from a heater box, but it’s used in various other places as well. I haven’t had any luck trying to source it anywhere. You would think a craft store like Michael’s would be the place but they don’t have anything close. And the problem with an internet search is you can’t really just call it foam. It returns 10,000+ pages.
If you have a link where I can find it that would be great.
The kit I used in 2007/2008 for our 67 ac car had multiple gaskets or foam sheet.i used most of thr fixed gaskets but replaced all the door foam or seals with quality stuff from mcmaster carr. The foam in our heater looked better in places than the replacement kit foam. I have no idea who’s kit or where I got it….maybe mustang plus who are long gone. It makes no difference any way, you want to use the best material you can find so you don’t have to do this again
