Few pics of the box
I had my box I. And out a few times spining the engine over with a spanner to see where the clutch hit the casing might be worth trying it with a spare engine if you have one instead of lifting the box in and out! Took be round five atempts to get it right! And dnt go mad with the casing other wise it will crack and spill geroil onto your clutch !!
If you need to no out else mate give me a shout!
