I've never been to this but they say it is one huge swap meet.  Admission is free, parking $5.  http://www.pateswapmeet.com/index.html  It's at the Texas Motor Speedway in Fort Worth, TX.  I'll be going unless something comes up.  There might be some Pinto parts to be had there.

I just got back from the Pate.  Popbumper, you are right.  Not much Pinto stuff to be found but lots of Ford stuff in general.  I'm still looking for the guy that sells owner's manuals. I saw him last year at Cruisin the Coast but didn't look for one for my Pinto.  Mine is still in readable condition but my Miata needs one too.  The Pate Swap Meet is so huge. When I first arrived I saw everyone riding rental scooters and thought they were lazybutts.  Then I walked the rows for a few hours and those scooters sure look like they'd be worth every penny.
