Ive got a 74 dart that I am having a heck of a time removing the windshield. Of course, I'd like to keep it in tact if possible. So far, I've removed the molding and trim, and cut away the rubber seal on the outside of the windshield. I've tried cutting from the inside but I can't get my hand down in between the dash frame and the windshield in order to reach the seal with my knife, suggestions?
