KBW10E Transmission

[Croc2020]

Hello everyone.
I have been reading the forums for a while and have learned much. Thank you for all your knowledge.

I am trying to find the forward gear for a Kanzaki KBW10E (2.83 gear reduction
) transmission. It is currently being rebuilt and this is the last piece of the puzzle. The transmission fits onto a Yanmar 3JH2-E. As the forums show, this is like finding a unicorn. Engine/Transmission specs are attached as a pdf.

If someone has any contact information for someone that might be able to assist, it would be greatly appreciated.

Thank you.
