Yo! i'm thinking of replacing some of the seals on my doors as well. The seals at the bottom outside of my windows are shot on about three of four doors. everything else looks about fine. I think the 'scraper' bit you mention is part 80820 and 80821 in this parts fiche:

Maybe that helps? i'm going to try and find some junk yard parts or just ignore it, not sure how far into the door you'd have to dig to replace them. I guess i was kind of hoping to find a quick cheap easy fix , you know, the holy grail lol.
