you can remove it from the top with the gearbox still on too Mitch...just gotta man handle it a bit more!!
Theres no right or wrong way of doing it...I would be here all night typing if i was to pm you!!Its all in the planning!! Work out a plan, work in sections,it is very easy, once you work out your plan of attack....most time is spent/wasted, thinking-what do i do next/now?? Just take your time and do what the others suggest and mark as much as you can if your not familar with it. The cardboard idea is a good one!
If you werent so far away id come over with my mate JD and help you out....
