Does anybody know what size spline key I need to remove the six bolts holding the driveshaft onto the transmission? I have a 2004 Alhambra 1.9pd SE with a clicking noise when turning and a ripped inner cv boot (I'm assuming this is the culprit for the clicking and it does have a little bit of play in it) so going to replace the driveshaft. I have read somewhere they are 12 point M10 but would like to be sure before buying one. Thanks
