Use a TT flywheel if using a TT gearbox, if using a n/a gear box can use either but if TT one is used you will have to space the starter out 2-3mm.
As for other parts needed:
Clutch peedle/box
Clutch master cylinder, slave cylinder
Clutch fluid lines with brackets and heat shields
Alternater Harness
Shifter Holder bracket and dust boots
Manual center console
Drive shaft ( n/a vs TT are different )
Clutch kit
Spigot bearing
Engine backing plate
You will also need to do some wirng to get the reverse lights to go.
I think thats about it .... OH and take the engine out, makes life a lot easier
