I E-Mailed Steele Rubber Products looking for a set of window sweeps for my 1985 Cutlass Supreme Brougham (should fit 81-88) and they say that they do have them. I know a lot of people have been looking for them as most sites only have the ones that don't use the wide door top trim pieces. Anyhow, here's the E-Mail I received back from them, complete with part number:
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,
