Duster windshield removal/replacement
Well I can state for a fact that just a gasket will NOT seal it from leaks.
My car had the glass installed after restoration, no bedding. On the road home from Carlisle 2023 we hit rail the last 100 plus miles and the water was pouring in from the lower corners, front was worse than the rear.
So, use bedding as stated in the FSM and drive with confidence that a water leak will not ambush your weekend drive.
