That would be my suggestion go to ebay look around for a Exedy or XTD. I was just researching your clutch and XTD has a complete kit with throw out bearing, pilot bearing, stage 2 clutch, pressure plate, and the alignment tool. When you yank your tranny make sure to inspect the oil. If its dirty change it with a good name oil. My other suggestion would look around for a LS or D16 tranny. You need the flywheel too make that swap because the D16 clutch is slightly bigger and the tranny input shaft is about 1/16" longer than the D15 (at least thats what I measured last night at like 4am might not be so dont quote me on that part) good luck
