haha, for competition use it's going to be an excellent feature for certain! You would receive the gearset, with shifter and the gear indicator is optional. It fits in existing standard cases, has its own end cover (supplied) to house 5th & 6th gears. It would need x2 bearings to suit the C64 along with reverse lever arm, the rest are C52 items. All parts are available yes, we can install in house. For anymore information either give me a call on 01925 822 266 or email me at mike@tuningdevelopments.co.uk Thanks Mike
