I've cut back on the number of swap meets that I go to. They used to be 90% car parts. Now they're 20% car parts, 20% tools, 10% yard equipment, and 50% garage sale items.
Most of the car parts that do show up are either for GM or are in such poor condition that you'd be better off buying new instead.
One other score we made at the swap meet was a set of tail light bezels for my buddy's '71 GTX. I'm sure I overlook some good stuff as I'm winding through the aisles but they just happened to catch my eye. Ray (my buddy that went with me) got them down to $25 for the pair. It was his '71 GTX that we'd installed the headliner in a few weeks back. He was going to run his car without any because one of his was mangled. He also managed to find a pair of very nice 15 X 7 Magnum 500s for $60. They didn't have center caps but the chrome was good with no rust or pitting.
Whenever we go to swap meets together we joke about who will spend the most and come home with the biggest scores. He was winning until I found those fenders.
