I'm the original owner of a 1973 Pontiac GrandAm, 4 door sedan. I took delivery in the Spring of 1973 in Gresham, Oregon. It has a little over 110,000 miles. I desparately need new door seals for all 4 doors, top and bottom. Anyone have any ideas? I've searched the internet with no success. All I can find is door seals for the 2 door model.
