Wow that looks crazy! I've only fixed 1 manual transmission and it was quite the project. However, I ended up buying a complete rebuild kit then taking apart the whole thing just to find a couple bad synchro springs causing 3rd gear to grind. Felt good to know/find something simple. In your opinion, are manual transmissions easier than automatics to rebuild/repair? One of these days I want to tear into a broken automatic to see what's going on in there, and maybe fix it if possible lol.
