I had 10 Aero small rear window gaskets reproduced at a cost of $160 per gasket, including freight to me. They're good quality and fit my window opening nicely
Unlike the narrow lip gasket for the wide rear window with interior window trim, these have the correct wider lip to better retain the headliner cloth around the small rear window. They have a slit for exterior stainless trim but it's very thin and barely noticeable, so these can also be used on the plain gasket cars.
When they're gone, they're gone. I'm keeping 2, and don't plan to reproduce them again.
Your price is my price, $160 plus shipping to your address.
