mkoebra95, I see you are in Maryland. I'm in Ashburn, VA. I have a 64 hardtop. I "finished" restoring it in March and am driving it daily.
I've bought a few parts from Thunderbird Headquarters and never had a problem. My favorite is
Mac's Antique Auto Parts in Buffalo, NY. I also use
Pat Wilson's Thunderbird in NJ.
Bob's Bird House is another in Delaware. All of these, at least, are on the east coast.
Good luck.
