The video did not show you how to adjust the lever/handle stops. Is the front stop bolt missing like your picture shows? I think they are a 3/8" fine thread, I may be wrong, check. Those 2 bolts are stops, so that when you hit a shift hard, the bolts are the stop, not the synchronizer. If a bolt stop was in too far, it would stop the synchronizer from completely engaging the gear. Loosen the lock nut on the bolt and back the bolt out. If your linkage is adjusted correctly, put the trans into 2nd gear and hold the lever/handle back in 2nd. Now screw the bolt in until you feel it hit the lever/handle, then tighten the lock nut. Do the same for 3rd gear position. I am not out in the garage, and it's been awhile since I have done this. I don't remember if the front bolt is for 3rd or second, or visa versa. Experiment. Or I can look at mine later when I go out to the garage. Make sense?
