I have two Bear cat secondary clutchs with knurling on the top edges of the clutch , I was told that these were done by some guy out west. I do not have any use for these and I would like to sell them, they will be just the clutch no helix or spring, 175.00 a piece plus shipping. contact me at burkysplace@roadrunner.com or 419-212-2450 , I can get pics of them if needed.
