Any Mopar parts businesses?

I am looking for a couple of parts so I can get started on my Duster. But after looking on Ebay, and several other sites I still can't find a couple of parts. Does anyone have an idea if there is a company that sells used parts. I have checked Year One, Dantes, Herbs, R/T Specialties, Dr Mopar and a few others but I can't find the following.

Shift linkage for console auto
Bucket seat tracks for 70 A body

Any help would be GREATLY appreciated!!
THANKS IN ADVANCE :thumleft:
