[67chevy1series]

SORRY FOR THE LONG POST
(im not trying to post a what its worth) my dad found a truck and it was in the junkyard, and he said it was a 67 cst ,i didnt beileve him until i told him to get some parts from it. one of the things i told him to get was the glove box . i looked at the spid and it said camper nameplate but it also said, custom sport truck, and it said it was a half ton, (i decoded the vin) so what i wanna know is how many of these were made, does any body have one if so, let see some pictures .
