Have you tried the advanced search function on the above website? You might be able to find your part (s) using it. They have schematics that are very helpful.
Not sure which handle cover you are talking about but i just messed around with the search engine for a few sections and came across some cover that might be the part. It's under Rear Door--->Interior Trim.
Maybe you found something I couldn't, but the advanced search only lets me search by part #, which I don't currently have.
I found the schematics, though, and while those would help with most pieces, they didn't seem to show/ label the actual pieces I need, including both the 2nd row captains inside armrest bolt cover and the front passenger door panel bolt cover (my own descriptions- I wish it was that easy to find under those descriptions).
If I have time this weekend, I might try to take the existing parts off.
Any luck on trrim pieces. I need some of the arm rest bolt covers as well.
Outerorbiter- if I figure out the part number, I'll let you know.
