So I have a little project that I'm undertaking and have run into a little snag. I have a WC that I can't get to shift between any of the gears. I had another shift tower laying around from one I had for parts and was going to change it out to see if that was it...and the reverse lock was intact on the new shifter. So I remove the old one and check the gears themselves to see if they slide. Yes they do so I don't think it has anything to do with them. I go to install the new tower and line up the forks the the grooves. Finger tighten the bolts and give it a try. Nope...still won't go into any gear. I have a running, driving WC so I know how it should somewhat feel like...and this stays locked in one spot or just 1/2 gear. I tool the tower back out and can't seem to move the shifter at all outside now either. What am I missing?? I feel stupid that I can't figure this out. It seems like it should have been easy Thank you in advance for any help you can give. In the last picture you can almost see that the pin in engaged into the 1/2 gear shift fork lug.
