I’m looking for a source for the felt-like material that goes in the rear window channels for my 1965 Dart GT. It appears to be stapled in, as you can see in one of the pictures. I’d also like to know if there are any tricks for installing the material, as it appears it is stapled in before the two halves of the channel are spot-welded together. If I have to drill out the spot-welds to do this right, I will.
