I'm not sure what part of CA your in, but there are quite a few of the 60 - 66 trucks still around out here. If you look on craigslist, you will will find a guy from down toward Riverside (LA) and one from up near Stockton that have been dealing in 60 - 66 parts for a number of years now. Depending on what your looking for, this stuff seems to turn up fairly regularly on craigslist, if you keep an eye out for it.
