I tried loosening but still couldn't get to the necessary angle so I took it off again and tried to get those 2 bolts in first , don't think managed to get them as tight as should be but the rest should hopefully compensate, I'll fill her up with oil tomorrow and fingers cross no permanent damage from running a bit on no oil...
If the pair of sump bolts are the ones that the flywheel makes impossible, instead of bloody difficult to get to.
The back of the flywheel has a pair of slots to allow access. Rotate to find.
