Hi Conor,
I did this to mine a few years back.
I went the easier route of using a left hand drive MT75 gearbox, otherwise you will need a UK specific DOHC sump for your engine.
I'm afraid I can't remember all the details - there is a lot, quite a long list of parts when you get into it.
What I can remember off the top of my head (it's early!)
MT75 gearbox.
MT75 propshaft.
DOHC Flywheel.
DOHC flywheel bolts.
Spigot bearing (for back of crank)
Clutch kit.
Clutch cable.
Clutch cable dust boot.
Clutch cable grommet.
Speedo cable.
DOHC sump & gasket.
I really can't think at the minute but that will give you a good while on ebay
