I bought a cheap crowbar from Home Depot today and cut and polished it into a nice new bucking bar that will now reach to the rear spar when I have my arm in the second row of lightening holes in the ribs. I was able to easily set the 3 remaining rivets along the rear spar on the bottom of the left wing in the wing walk area. This worked out great so I didn't have to use pop rivets in this boxed in area after all.
