If it were my car, I'd try:

1st - Cotton Pickers. Call and get straight to the point. That guy doesn't like idle chat.
2nd - Deering Auto clear out in Spicer. You'll have to call, but they run an ebay store. Probably need to talk to the son about what exactly you're looking for.
3rd - Pam's Auto. Look online or call. Local, but expensive.

Good luck!
