Hello, your English is fine 
I'm sorry I do not know about transmission systems, I just wanted to say how beautiful this is....this your K12?
I assume if you are changing the whole system? that means new gearbox, new clutch, new flywheel ...and more?... big job?...
I hope you find the perfect one to suit your car
maybe somebody else here will know, and be able to help you with this
Good luck friend
