If you had gotten a new flywheel (like you should have) this would not be an issue. I really hope for your sake and your new clutch's sake that you at least get your flywheel resurfaced.
TBTH to save on return shipping costs I would just buy a new flywheel and there you go.
Just FYI and for anyone else looking, any 96-early 01 should be upgraded to an 11" setup which is just an 11" flywheel and clutch. You need nothing else. Price is nearly identical and you get a little more surface area/more power handling capability.

Just because I give you advice, doesn't mean I know more than you. Its just means I've done more stupid ****.
