it'll be ok having odd driveshafts, but if m10 bolts wont fit through the driveshafts cv (unless you can drill out the holes) then it wont fit.
both shafts are listed in etka as having m8 and m10 versions, the one youve been sent is for
AHW,AKQ,AGP,AQM,AEH,AKL,AGN,APK,AQY,AGR,ALH,AHF
it will work with your engine, its just these versions need an extra wide cv for some reason
