OK, the door trim pieces are still on the doors. Tomorrow, I will work on getting them off - hopefully, with the mounting hardware as well (it was ONLY 105 in the shop and VERY busy today).
For now, here are the quarter trim pieces.
"Pretty" sides:
"Back" sides:
As you can see, my idea of 'carefully' removing them was to simply cut the quarters around them. The piece you're wanting (bottom of the pics) I was able to remove from the sheet metal, but I have no idea where the mounting hardware is (probably fell apart, as you can see how bad the sheet metal is/was). It's in pretty good shape, and will require some polishing to make it nice - but everything you see is pretty much just years of schmootz and should clean up pretty nice. There are some minor scratches on the end by the wheel well opening, but the discoloration is mostly just dirty ick and should come off OK.
My plan is to just send them as they are (sheet metal and all) and you can separate them yourself (so I don't mess 'em up in the process).
If you also want the door trim pieces, I'll find a box big enough for those as well - but if you only want the quarter trim pieces, I'll send them as you see them. Either way, I'll get 'em in the mail this coming week.
Hope that's what you're looking for.
