idrivemopar has had a thread going on about his rebuild and in his thread he talks about where to get the products you asked for. In his thread, the info starts on page 7, frame 130, and goes for some frames. I found it valuable cause I too bought my products from Steele Rubber and Restoration Specialties.
Here is a piece of the discussion.
If you are looking for the drip rail weather strip, get the ones from Steele Rubber and not metro, metros don't fit too well, but the Steele Rubber ones fit right in. The metro door seals that go around the bottom edge of the door fit good, but use the Steele Rubber end seals/caps. If you are doing the belt moldings, get the ones from Restoration Specialties, they are the best fit and quality. You will pay a bit more for Steele Rubber and Restoration Specialties, but its worth it so you don't have to force things to fit right.
Hope this is what you were looking for.
