72golddustermike, I had this issue with my 66 Satellite. The gasket would conform on the sheet metal side but would pucker on the under side of the glass, in the lower corner. I determined that the gasket had excess material on the flange that goes under the glass (needed to be shrunk if it was a metal part). We carefully cut a small pie out of the flange with a razor blade where the pucker was most pronounced in both corners. We started small and increased the size of the pie until the flange would lay flat. If you are careful with the cut it is almost invisible. We did not glue the flap back together as we only cut it down to the start of the glass channel and sealing was not effected. If you wish to glue the flap o-ring glue will work, which I believe is just super glue. Hope this helps, Brian.
