Given you'll need to take the body off to do the AC pipes anyway.
If you were doing just the box :
- Flywheel / clutch
- Gearbox
- Pedal box
- Check wiring from clutch pedal to handbrake module and loom if necessary
- Update CCF to remove transmission ECU
- Interior console plastics
The interior console parts just clip on and off.
Then you get a nice manual HSE with all the fruit. I'd put a new flywheel & clutch in there while I had it apart, but that's just me.
The ducts don't look too onerous. Looks like the roof lining and C pillars need to come out.
