Gear box bell crank assembly. Upgraded part. Improves gear selection. (please note 2 rod ends and the roll pin  supplied with this kit) With this kit you will improve the feel of the gear change. 

This is a unique design from Mike Satur with new angles and lengths to ensure the gear lever is in the correct orientation ..some aftermarket ones are not made the same and just copy the original part so are less effective that the MS design.

Now even cheaper due to better manufacturing methods.
