In 1974, I replaced the headliner on my Ponton 180b. This involved removing the back window, but I was able to secure the front portion under the inside windsheild trim. That original Ponton headlining, like the one in my '60 Fintail, was a cotton velour. I used it as a pattern to make up a replacement from nylon velour, which looks like the original cotton but doesn't rot. I've got similar plans for my Fintail.

Happy Motoring, Mark
