Well, I looked at the car again today...no sign of a tag on the firewall, nor any holes. And no sign of a fender emblem ever being on it. But I did discover that this car was originally a single headlight model, that was changed to duals. The single headlight fenders had the backs cut to accommodate the larger dual headlight buckets. Then everything was sprayed with undercoat. It appears that it has been this way since it was converted...
