i've taken some 220 grit sandpaper to a clutch before (for our GRM 2007$ car, and for my old daily driver).. i sanded the flywheel (orbital sander), clutch pressure plate surface, and the clutch disc (lightly)seemed to work fine.. it probably would have been fine if i hadnt, but all three parts were used, and had never seen each other before.
budget budget budget.. good luck!
