I have both the new windshield and gasket. My Apache has the stainless Deluxe trim to go around the new windshield. Does the gasket go on the glass, then in the frame? Does the stainless go in after the windshield is in or as a unit? This truck had nothing installed when I got it. I have read enough to know I want to get professional installation but want to insure I understand the correct procedure when I talk to them. Appreciate the help. Ralph
