Riveted 18 nutplates around access openings for mounting LH & RH Steps. Challenging since a standard 3" yoke in the Main Squeeze was slightly too large for opening ( a 2.5" would have been OK !). Had to shift to Rivet Gun and bucking bar. Even my titanium bar was too long for a few locations - and otherwise was a bit awkward to manipulate and hold in positions. A couple locations required using a small steel bar I had from working really tight spaces on the Empennage - on it's narrow edge. It took longer than expected, but persistence paid off.
