I am restoring a 1982 Buick Riviera convertible and searching for a replacement header seal. There were so few of these convertibles made, no one is making reproduction parts for them. I have come to the conclusion that I will have to try and fabricate a header seal using the molded ends of my existing seal and inserting an extrusion. Has anyone else had this problem and if so have you been able to come up with a satisfactory solution? buickbob@charter.net
