"Kevin.... There should be a 3
"Kevin.... There should be a 3/8" hex head bolt screwed into the side of that clamp, which is actually a long shoulder bolt type screw (a pivot pin). Sounds like you removed the bolt that faces forward, the one that clamps the shift lever to the shaft. The 3/8" shoulder bolt is reached by using a long 1/4" drive extension with a 3/8" flex socket. You'll also need the long flexible "finger" type grab tool to extract and insert that shoulder bolt.
