As above, what mods are required to fit a TKO600 into a 2WD saph?

I already have:
Bell housing converted to a T5
Clutch plate
Brass spigot bearing.
Gear box cradle.

What i am wondering is what do you do about the gear stick? I belive the stick will sit about 50mm further forward, now do you need to trim the tunnel or is there anything else that can be done? Like having a special gear stick made or machining the housing?
