I used my laser leveler to locate holes for my tow bar attach tubes. First I centered the laser's red horizontal and vertical lines on the attachment lug, then installed the fairing to the nose gear. I the marked a drill-point where the two laser lines intersected (right on top of the lug). I did the same on the other side. I then removed the fairing and drilled a 1 inch hole at the marks.
Image 3 shows me heating shrink tube on the ends of the tow bar tubes. This should protect the fairing when connect the tow bar to the nose gear.
