OP. look in the transmission forum. You should get a TSK3 TOB kit, 07-09 flywheel and a good clutch kit.
IMO do not use a OEM clutch.
Also buy from one of the vendors that support this forum, or contact Mike at AZPinstalls.com if your on the east coast of m sprank if your on the west coast.
They help out on here a lot for free.
