I've done exactly the same in the past.

Here is more or less the only place you'll get one, and people don't tend to like breaking engines into their component pieces much so it might be a bit of a wait! Maybe contact the affiliates

(woodsport, sbits, pacific works etc) to see if they've got any spares sitting around

- that's how I got mine.

I take it you weren't following the procedure from the workshop manual

- you're meant to go around them in order tightening them a little bit at a time! I know I wasn't following it when I snapped mine off.
