Spent an hour assembling the tools (mainly a torque(?) drive) - took the broken one off - this mechanics lark is easy-peasey. Fail, it's the wrong type of visor (too short). Pulled the bracket out of the old one and it seems to work just by friction - so another half an hour borrowing a pair of pliers (mine have disappeared) and a good, grunting squeeze and hey-presto it stays in place now!
Took off the exhaust shield too, which was rattling like a demented pneumatic drill.
I think I will get the garage to fix the rattle from the front suspension
