JWest original design replaces the factory throttle bell crank that is mounted on the side of the gearbox.  Adjustable angle and lever length allows you to adjust for ideal throttle motion and to attain full throttle - have you checked your car for full opening lately?  High-precision and silky-smooth. Bronze bushings ride on a machined shoulder bolt. The factory uses plastic bushings and is retained by a cotter pin with a very sloppy fit. You can feel the difference in your foot. 

There have been a plethora of different bell cranks made by the factory over the years. Finding the right one for your car can be impossible, especially when parts are swapped. This replaces them all!  Also allows for increased throttle response, adjust the slow low-throttle progression if desired. Works with all Porsches that utilize this type of bell crank - 356 (typically '60-'65 741 gearbox), 911 through '89, 912 and even 914-6.
