If you are in the area at the right time check out the Pomona Swap Meet.
Next show: http://www.pomonaswapmeet.com/ is July 13. It's hotter then crap during the summer in Pomona, Ca. The show is unbelievable. I always recommend the show to motorheads who are not from the SoCal area. If you do look me up. I will go with you. There's anywhere from 500-1000 cars for sale and 500+ people selling stuff.
