While Stu and I were visiting at the Scarsdale Concours last month, a fellow GT owner checked both of our cars (before Stu got his second GT) and informed us that we were both missing the rubber "seal" that keeps out moisture from getting into the gas tank (not that many drive them in the rain). I went to the local Ford dealer and they checked the parts list and did order it for me ($24), I'm due to pick it up either today or tomorrow. How many of you out there are also missing this little rubber part? When I pick it up, I'll post the part #
