Here's a good one for ya! 70 Chevelle with antennae in windshield. Hole in cowl where lead from windshield plugs into cable going to radio inadvertantly got welded up ! (long story) Nothing in assembly manual or doing a search. I need a pic or measurement please. I can tell where Approx goes, but need size of hole (1/2" ?) and how far out from windshield. Any help much appreciated.
