The typical shift lever has a ratio of approximately 4.5:1. That means if the action (keyframe) is shifted 0.1” or so to the right the end of the shift lever under the pedal rod will be off by 0.45”. Or, if the keyframe shift block (clutch?) is worn by that much the shift lever under the pedal rod will also be off by 0.45”. <o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Comic Sans MS";color:navy'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Comic Sans MS";color:navy'>Before you simply start adding leather spacers to the long end of the shift lever you might want to be sure there is enough room between the top of the lever and the bottom of the keybed.
