I spent a day with Steve Simmonds years ago when I wanted to learn how to fit windscreens in Morgan's. Steve showed me a couple of the 'dodges' the first was to get a wide strip of the rubber seal, he said the OE stuff is about an inch wide and he used seal rubber that was at least 1.5". He folded this over the screen and held it in several places with masking tape. After fitting the glass to the frame he simply trimmed off the excess inside and out with a razor blade. A good watch point is ensuring the glass is the correct way round as the inside and outer pieces are tempered differently, he says its seems a joke but even he has done it! ;-).the masking tape edges can't be seen once rubbed with a grubby finger ;-).
