Well... whenever you do the clutch you SHOULD do the flywheel too, or at least have it resurfaced. But if you are selling it I'd just do a $120 Luk Gold clutch, slap it in and hope you have access to a lift to do it for cheap vs $$$$ to have the labor done.
And **** like this is why every time I think of selling my car I start second guessing. Too many boy racers would show up just to go for a ride... I generally include in any ad I post for sale "no joy rides, test drives only after you show cash, be prepared to go to the DMV upon sale to transfer car to your name". This usually keeps dip****s and tirekickers away but not always.
2000 Mustang GT Steeda build #48. Bolt ons, suspension, Novi 2000.
Just because I give you advice, doesn't mean I know more than you. Its just means I've done more stupid ****.
