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.
