Brought the discussion over here...
I'll be over there getting my car in a bit. Will try to get a pic of that and a few other things.
I never knew of the antenna being different. As for the lenses, I have talked to other owners that were sure theres were original and were not what is supposedly correct. No doubt stuff was done at dealer or just because they had parts left over, etc. One example is the 74 front bumper. Early 74s have the big blocky guards and no shocks. From what I gather the changeover was sometime in Spring of that year. If you look at the bottom of the Flash grille, it is blacked out. We even checked it on the 1975 magazine pic and it was same. Mine is argent silver. Possible the black paint weathered off over the years. Want to check what the feather has.
