There are 5-6 countersunk screw holes behind the windshield frame on the cowl/windshield lip. the screws are machine screws that fasten into bars that hang behind the dash and basically cinch the dash to the cowl. I made my own out of 3/16 stock 1/2" wide and 2-1/2" long..I tapped them 10-24 just high of center. Its basically a bar that acts as a nut.

If you look at the back of the dash you should be able to vision what I am talking about. Maybe someone else has pictures of the real factory fastener.. this is just what I did..

Also I ran a sticky backed piece of weather stripping 3/4" wide along the top edge of cowl the seal the area.. there was some sort of cloth originally I believe.. Tom
