We just removed both front and back glass out of my 69 valiant 4dr. Saved both glass and gaskets.. I have to give oldmanmopar ( Steve ) all the credit. He is the man when it comes to these old cars.. Once the trim is off and lock strip undone he used a paint stirrer that was round on one corner. And sanded down both sides of the rounded corner like a wedge. With the paint stick and dish detergent on stick run it between the gasket and the glass on both sides. Also used wd-40 on the inside for lube. Once that is done one guy pushes on one upper corner while the other is using paint stick. Once you get a corner out work it all the way across the top edge and it comes right out. Very messy but it gets it done.
