Long story short, son's car has a big crack in the screen. It's a 1990 Alfa so it's a rare car to start with. The screen has stainless trims round three edges, which are no longer available so I'd need to cut the old ones off the old screen and clean them up - plus I might need to treat some rust under the screen, if there is any. For those reasons, I'd much rather just buy a windscreen and fit it myself (I've done this before), but I'm struggling to find anyone who will only sell me a screen now! Last time I did it, my local National Windscreens place got me one, but they're no longer trading.
