bell housing can stay put
1. unbolt exhaust from exhaust housing on turbo
2. unbolt gearbount mount
3. unbolt prop
4. you might have to split the gear lever 2 13mm bolts from inside car (cant remember

)
5. unbolt gearbox and should have enough room to get the gearbox under the cross member
that's how i dont mine on my saff and it saves having to take the exhaust off completely
this is with me having full workshop facilities though, and i wouldnt want to do one on the deck!! you're a braver man than me in this weather
