(page 6-06 revisited) Ah $&%#.......           

...as they say in the comics.  Somehow I missed step 9 on 6-06 which instructed me to flush rivet the previously dimpled nut plates to the skin prior to riveting the skin to the v-stab skeleton.  I was able to get all but the last two, but the rivet squeezer won't fit into the upper end where the space narrows.  I'm trying to locate a smaller squeezer which will fit.  If necessary, I'll buy the smallest I can find and grind it down.  Worst case, I believe I could make one from vice grips.
