yes wrong bolt that one is under the starter motor .:doh:The other problem is the 'bastard bolt' (as smo named it lol).
I'm sure its one of the starter motor bolts that is rediculous to get undone as you have no room to turn it much.
Or am i getting mixed up with one of the bell-housing bolts that is situated right near sensor and starter motor ?
good luck anyway chap .... just bump start it for now lol
