Photos of gears can be deceiving so I can't tell what all was affected or how badly. I looks like there are some dents or gashes in the tips of some of the teeth but it's hard to tell from the photos. The piece appears to be a washer or shim. It's also possible that it may be a retaining ring for the rocker but I can't tell. From the patterns of the paper towel, it doesn't appear to be very large either but it doesn't take much to beat stuff up. It would be interesting to find out where that piece came from. The synchros and the forks show some wear but I can't tell if there is any damage.

You will need to find one of the guys that modifies these for early Ford applications to be able to get gear parts unless you purchase a good used unit and trade out parts. Ford doesn't stock them anymore and I don't know of any aftermarket manufacturers to date. You can get gaskets and seals but hard parts are another thing.
