Tonight I finished the two z-brackets that had to be re-done and installed the nut plates that I was missing. 

The spar was fairly easy to countersink for the nut plate rivets, however the outboard rivets have to be done without a countersink cage.  Use a sloooow drill and its a piece of cake.

Unfortunately I cannot say the same thing for these rivets.  I had a heck of a time getting these rivets done and it took me way longer than I wanted.

I also drilled and affixed the nut plates to the capacitive fuel sender plates.
