windshield antenna connector source?

[coldair85GN]

A long story made short...I've replaced multiple power antenna's on my Buick since owning it and I don't want the hassle anymore, plus I want to cover the hole on the fender when I paint the car for a cleaner look. I am planning to replace my cracked windshield after new years with one that had the antenna built-in from the factory but I don't know what connector is necessary to plug in to the windshield. Anyone have an idea?

Mine had the chassis connector already installed underneath the cowl panel.I used it or a few years while my power antenna was out of commission.Yours may have it also.

I shaved my power antenna hole on the fender and it looks great. I'm going to add a signal booster above the headliner
