This is another picture of the input shaft:

I think it will be alright though. It looks more like a broken piece/defect than something that was supposed to be there.


This is 3rd gear. It looks decent to me and just like the rest of the gears. the inside of the shift slider also looked pretty good.


These are the syncro keys for the 3-4 syncro. they all have wear but the one on the right looks worn out. I will definitely replace that one.


These are the syncro keys for the 1-2 syncro. This one worked fine with no noise, and the surfaces of the syncro gears look good on this one. I think I will leave these keys.

Thanks for the help guys. please let me know if there are any other good sources for the parts i need other than Brewer's.
