Hi people! I need definetely to change my gearbox, and i'm looking at my junkyard's web site, and they have a few 1.3 gearboxes, with different numbers. All that i could find is, at the left wheel side, is a AK 50Y badge, is that the number? Also i found at the top mount the engine code, CG13, and this number: J421210. None of the numbers of the junkyard appears to be the ones on my K11: 341942 / 9521300pd and 209635 / 9z11364
