I’m putting in my headliner and in several installation videos they say to wrap it over the edge of the windshield and back glass opening and installing the glass over it. I know on earlier years with gaskets that’s the way it’s done but with the windshield being a glue in, is that the way to do it? My glass installer who specializes in classic cars says not to wrap the headliner over the windshield opening but it’s fine for the back glass... my question is how was it done by FORD?
