Theres not heaps... If your S60's already a manual then most of the work is done, even the driveshafts are the same. You'll have to convert to dual mass flywheel, different clutch etc, you'll need a shifter from a 6 speed model (easily sourced from the UK, I do have a spare but I'm keeping it in case my 585,000 mile one that I currently have decides to break!)
