Hi Steve, Hi Jeff
It for a wet clutch MC18. Jeff's right, it's the external rod (about 10 inches long) that connects the external gearbox shaft and gearlever. It attaches to reverse threads at both ends.
Any chance you could send me a pic of the one you've got Jeff? My email is jim.moore@emap.com
Only snag is that I'd need it by Wednesday coz I'm going to the Llandow trackday. If it's the right bit, could I pay you through Paypal?
Cheers
Jim
