65 Dart Radio Antenna Location

My car has the radio antenna in the rear quarter, which I must admit looks pretty good. Here's what my car looks like with the antenna in the back.

But, I'm doing an original restoration and so I think I should move it to the front fender. Trouble is, I have two fenders and neither one has an antenna hole. According to the fender tag, the car came with a radio, so I'm guessing the fender was replaced at some point.

Anyways, I'm wondering if anyone can upload some measurements for where to put the hole. I need the diameter as well as the location.
