zenith cruzer landing gear strut attachment

 I am installing the main landing gear brackets and the plans call for 5 A5 rivets at the top of the gear strut fitting (LS75F14-3A).  There are five pre-drilled A5 holes on the outer skin but they are at a 10 deg (or so) angle (see photo below).  Should I be drilling new holes that are parallel (i.e. the RED line) with the bottom of the skin and the top of the gear channel (LS75F36-1) OR should I just use the pre-drilled holes?  The last pre-drilled hole on the far right is maybe 10 mm from the top of the strut flange (or so).
