I lived in San Diego from '83-'87, worked on the car crew a few times a year when S&S came to town to shoot locations, got to look at the truck up close. Though it looked pretty beat onscreen it was a clean low-mile (16,000 when I last saw it) truck bought from a used car dealer on Lankershim Bl. a few miles from Universal Studios, The rough appearance was aided by a simple weathering process that included flat clear Krylon though it did look pretty beat after seven years. The front bumper was removable for use when 'front shots' of Rick and AJ were necassary, the truck had standard towbar mounts behind the 'plug-in' bumper.
When the series finally went off the air in 1988, a year late due to the WGA strike, the trucks were sold at auction, the better was bought by a guy in Hollywood who used to park it on Cahuenga Bl. out front of his record store. Looked cool there.
I built models of the truck and the Camaro from the series, displayed them at the Toledo NNL in '84 or '85, maybe Tim Boyd or someone who was there has pics?
Probably the best shots of the truck are on the shows themselves, first two seasons now available FREE on Hulu... Fun stuff, good luck getting the theme music outta your head!
