Hello, Does anyone know of a previously produced 5-speed straight cut gear kit that will fit properly into the 56 or the 60 series gearbox cases? I had heard rumors over the years that a Spanish or Portuguese company made these, but I have been unable to find any.

Any leads would be appreciated. Thank you, Peter

Dont know if this is what you are after but they
supply Japan and Eu companies as their SC gear
prices are cheaper than any in the world.

these guys are ol sckool wont answer emails but
traditional phone and human2human thing

1k usd for complete gearsets was cheap even in 2015
when I arranged some for a friends Alfa 105.

Peter one of the Japanese companies was talking about doing this, I'd emailed them and asked them to keep me in the loop but never heard anything more.
