Hello Don (T800). I just revisited this thread after some time away, and saw your post. There are three options:
buy a replacement OEM mirror glass unit from a dealer. Ludicrously expensive, even more so if you get the dealer to fit it;
go the "scudney" route and source a replacement from a breaker (either the glass, or the whole unit - latter is easier for a breaker to supply and not too costly);
go for the quick and dirty option - especially if the MoT is imminent - and get a stick-on replacement glass from suppliers on the well known online auction site for a few quid. It just sticks on top of your existing faulty mirror with double sided tape and is perfectly legal.
Me? I went for options 2 and 3..... in fact the stick-on mirror is still in place two years down the track, and the replacement unit from a breaker is still on my garage shelf. One of these days (or when the stick-on one falls off), I'll do the proper replacement!
