Another Mopar Off My Bucket List - Barracuda Fastback

Guys I have a set of 15" Shelby cal 500 slots. I always figured they were aftermarket since
the fronts are 3 1/2" and the backs are 11" wide. Mine have the 5 ear caps that are held on with screws. Probably from the late 60s or early 70s?
Let me know if you want a picture of the shelby caps or something I could dig them out.
