Will the Hurst Mystery Shifter (293-3097) work with the 3 speed with OD transmission? The box says it is for the 9 bolt, straight bottom side cover, which my FIL has on the car but nothing about the OD. I have heard somewhere that if we were to put a floor shifter in the 55 we would need the Hurst Mystery Shifter. Will anything else out there work?
here is an ebay link to the 293-3097
