Thanks guys, I reckon I'll try and repair the mount, and if that goes horribly wrong at least I know how to get it out, I assume yours passes MOT without it?
I already have 2 spotlights fitted to the radiator which makes a huge difference, but I find that if I have them angled where it's best for me to see at night I start get flashed by oncoming drivers, so I have to settle for dodging mud and roadkill 20 yards at a time! (Still better than not being able to see at all though!)
