Where are some offbeat places to locate hard to find parts?

[MODO Innovations]

The obvious, MODO INNOVATIONS. Ok, Maybe just a few things.

There is a place on I-35 between Denton and Sanger, Tx. that is a salvage yard for old cars and trucks. I don't remember the name but I did stop in and talk to him along time ago. I asked if most of his business was out of state and he said no that most of it was out of the country. I know he used to advertise in Hemmings Motor.
He has probably 15-20 acres of old stuff.
