Alf Olav,
I have the XP-IO360-B1AA2, same sump and injection system.
Van's sell a bracket for the M1B which reverses the direction and connects to the mixture on the horizontal injection servo. This is a straight or at least very close to, fit.
The throttle bracket you have to make yourself. I'm just at that stage myself so can't help too much but there are photos and info on the yahoo group
http://groups.yahoo.com/group/XP-360Forum. You may have to sign up to see the posts and photos.
I have some photos of the mixture bracket on my site
www.iansrv6.co.uk and a few other photos of the engine install.
By the way, you'll notice I live not too far away in Scotland, I work offshore Norway and crew change out of Br?nn?ysund just now, I travel through Bergen and Trondheim every month. Where in Norway are you?
Good luck, might see you at a fly-in one day.
