Doing new door gl*** in 1927 Ford coupe. what wiper seals are best to use inside and outside of gl***. I have all the new channels and top seals but unsure about the wipers. I have the top chopped 6 inches and chopped the windshield that swings open. Any suggestions on seals for the windshield. The ones that Mac and others sell seems to slide in a slot. I see no slots on windshield or post. HELP!!!
