Stainless steel bolt, stainless nylock nut and 2 stainless washers for repairing broken MX-5 mk1 mirrors.  Note that this isn't exactly the same as the standard bolt, but then the standard bolt rusts away in the centre and snaps in half. 

To fix the mirror, carefully cut the black plastic surround from round the glass, remove the glass, take out the old bits of broken bolt and rust, replace with this new stainless bolt, tighten it so that it can still be adjusted but is tight enough so that it doesn't flop about.  Replace the glass and glue it back together.
