My friend's car that is a 1969 Six Pack Super Bee was bought off the lot on Sept. 9th 1969 by the original owner. It did not have a hole in the fender for a Ant.,it had the block of plate on the dash in the normal Radio location. I would imagine that the Dealer installed the Radio so it would be more presentable on the lot to sell. Usually Dealers would put the hole for the Ant. in the rear quarter when doing an ad on at the dealer of a Radio,much like an AAR/TA.

My 1971 Cuda came without a Radio. NO hole in the fender and a block off plate on the dash in the radio location.
