I figured I would post this here too as I know that a lot of people have been trying to find the window sweeps that go with the wide door top trim panels on the Cutlass and Regal doors. I wrote to Steele Rubber Products about them and they say they reproduce them. Here is the E-Mail I got back:
Thanks for checking with Steele Rubber Products. Part 80-0529-57 is the
set that you would re-use your existing exterior molding with.
Please let me know if I can be of any further assistance.
Thanks again,
