I put the 3spd column shifter back in my 50 today and the shifter box is mounted to the column. When I pull the shifter back to test motion, it doesnt pull back. I adjusted the shifter box fore and aft on the steering column and it changed movement slightly. I am thinking maybe there is a problem in the shifter box. Has anyone rebuilt one of those? I took the cover off and not sure how its supposed to look in there. Any thoughts?
