Anyone intrested check out ebay #4601402060. I also own a set of rear bumper guards like this that are solid and have no rubber strip. I found mine in a salvage yard in the mid 70's (that car also had a bench seat that I didn't pull). I have asked others for their opinion but no one seems to know what I was talking about. My 67 is a 3rd week of October 66 build and I'll have to do some more research to see when this change might have occured if legit.
