Hi there

Some scumbag knocked my door mirror off my car when parked up on the
street, breaking the aluminium casting which holds the rotating part to
the door.

Apart from buying hideous aftermarket mirrors, the only fix I can see
is to buy a new mirror assembly - #1 in

51&fg=10.

Does anybody know of any way this casting can be replaced, if anyone
makes one etc.?  Repair of the old casting is probably a no-no as it is
so thin and the distortion caused by welding will probably result in
poor fitting.

Any ideas?

Thanks
