when i change my clutch should i take the flywheel out and get it resurfaced or should i just hit it with 180 grit sandpaper and reassemble. also how tight are those bolts holdingthe flywheel onand how much torque is needed to tighten them

 

Resurface if possible

 

Definitely resurface it. Match mark it before removal to ensure it doesn't lose balance.

Clean both the pressure plate and flywheel with carb cleaner or brake cleaner before assembling.

Torques are listing in the FSM, which you can get from www.phatg20.net
