I'm looking at a truck that the guy has had for over 20 years. He says that the placement of the antennae on the truck is original for '67 chevy pickups. I don't recall ever seeing it on the fender. Can anyone tell me where the antennae was placed on a '67 from the factory? I always thought it was the same place as '68 - '72. If not factory, would this be a dealer installed or an idiot installed antennae? Any help would be appreciated.
