They were quite confident that they could adapt it, but since I didn't want to take any risk of having to open the clutch housing again, I told them to use the "Greenline-specific" part...which was specifically more expensive ;-( I'm only telling you this because, at least on my 2010 model, there was some small, but possibly important difference. So be sure to compare your old and new cylinders closely. Perhaps the cylinders were fully standardized by the time they got around to model year 2014.
Your Letrika manual makes me drool. I will send you a PM.
The one ordered looks identical to the one pictured in the manual. It does have "INT" after the part #, which I assume is for "international".
