Forks look womped. The synchro teeth on the speed gears are nothing to write home to mom about either. Input doesn't look horrible. One thing no one is considering is wear on the coast side of the synchro teeth. I cannot tell you how many gears we have canned with PERFECT points that popped out of gear because the coast side of the teeth are worn so bad. Put them in a box and send them over. I will gladly look at the stuff for no charge and get you headed in the right direction. By the way, it IS a 2.47 ratio unit. I am very hesitant to diagnose synchro teeth by a digital picture of an oily dirty gear. You just cannot see the detail needed.
Let me know if you need help.
