1964 Valiant "Get Runnin & Drivin"

Thanks. I am workin on it. I got the windshield channel repaired and I have both the gasket and lock strip. SO hopefully, the windshield will be in before long. I do have a question there though. About the headliner. I know it can be done with the glass in, but I really want to get the glass back in so I can drive it. Is the headliner install that big a PITA with the glass in?
Not sure if one model is worst than another, but I have done most with glass in, the sail pain area boogers me unless it has the cardboard part, A low heat gun helps get out wrinkles , let the headliner sit on a warm hood, have good glue. It should have a couple of wire hooks at the top of rear window so pull from that.
