I marked all skins placement and peeled plastic for the overlap on the right skins and started alignment on the right outboard skin. Odd thing the left side was 1 and 1/16th inches from the lower edge of the forward spar flange to the center of the rivet hole in the skin. It looks like the right side skin is 1/16th longer than the left. Before I drill that I am going to confirm that is normal/ with in limits. Good days work.
