1965 Power rear antenna

Hello... I'm starting in on a restoration of my '65 GTO and I'm planning to convert it from manual front antenna to power rear. I've found some pictures that show roughly where it's located on the rear passenger side, but I'd really like to find someone who has one from the factory and have them measure the exact location for the hole. Does anyone here have a '65 with factory power rear antenna? Thanks.
