I just removed the vinyl/cardboard door panel for one of my doors, after wrestling with the retaining clip on the window crank for 20 minutes. Of course, all 6 of the plastic retainer plugs are broken. Does anyone make these now, or is there a functional replacement? I image I'll need them for the other door when that one's removed soon too. Also, are these rings around the window crank reproduced or available? It was a casualty in the crank removal.
