Stick shake is a problem, especially with a heavy custom knob on top. Frequency vibes on the highway have the same effect.......so you just have to ride around looking cool with your hand on the ape hanger!
Got one for my Model A, but after installing found to was way too close to the steering wheel. Course, Model A's are pretty narrow. Swaped it for a shorter one and that works fine.
Hey Grant, wanna sell the long shifter? My dad has a 16" shifter in his roadster and wants the long stick. I'd guess you have the cable and detent that go with it, right?
