After cutting the tie down to length, drilled the one hole in the corner of the aluminum, and cleco'd to the spar. Then drilled all the rest of the holes using the spar as locater. Then removed the bar, and drilled the nutplate rivet holes, countersunk the proper holes, and tapped the end of the fitting for the tiedown ring
