Babbyblue,
Yes there were stock and SOME RARE. Most get scratched up and then the shrink wrap starts peeling, gets rusty and the owners pull it off and paint the covers. I have 3 sets of VC 1 Plaid, and 2 regular, one I'm having Chromed and the other is painted to match the engine as factory.
The only other parts on these trucks that is WAY HARDER to find is the Chrome Hood Ornamant, the Dinsmore Compass and the Electric Clock.
I have all of them and I'm not letting anyone play with my toys in the sandbox. hehehehehehehehe
