The optional bumper guards on this car confuse me. I've never seen bumper guards this big on a '69 Coronet before. The ones I'm familiar with are about HALF that size. Were there two different types of bumper guards available?? Are these correct or added from some other car??
I really don't think there is anything wrong with the fender tag, it appears to be legit. Cars that were built at the Lynch Road assembly plant were not coded on the fender tag like cars from other plants were. Many options on cars just plain weren't stamped into the tag at Lynch Road, you really need to see the broadcast sheet for a Lynch Road car to determine its build.
I'm convinced the bumper guards ARE NOT factory, they must be some type of aftermarket add on as Rich has mentioned earlier. I didn't really study the photos for other non-factory stuff, but those bumper guards just JUMPED OUT at me.
