well, whenever you do a swap you should always inspect the flywheel to see if it's warped, if yes then either buy a new lightened flywheel or get your current warped flywheel resurfaced, and have a new pilot bearing put in. Clutch wise I just see it as a better option to just have a new one installed since the motor is apart anyways, no need to do things twice, especially for 300 bucks.
