The trim pieces are replaceable, held in by about 8 or so screws. You remove the door card, pull back the foam and they come out easy. Tricky part is often trying to find them being sold individually, as normally people only sell em as part of the complete card.
Pretty much all the rest of the card is plastic welded together. I replaced my white stitch trim sections with red ones and spent a good amount of time melting the old tabs out, then re-welding everything together with Polypropylene welding rods and a soldering iron.
Tighter tolerances than the factory now though, and not a peep out of em over a year later
