At some future point I may be replacing a the flywheel and/or clutch. I have a few questions: -How much time should I plan on spending to replace the flywheel, clutch and related parts(I haven't done this before although I have removed a powertain)? -Should I replace only the flywheel if the clutch still seems good?
