Was there ever a "no radio installed" option?

My 73 Dart Sport did not have a radio. The dash panel did not even have a provision for the radio. The passenger side fender did have the antenna hole punched in it with a die cast plug. My guess is that the factory thought that by punching the hole in every one was easier than trying to match the fender with a radio option.

I found this online, in another old Mopar forum. This is exactly what was in my '75, and I would really like to find one.
