Well dangit! I drilled the inboard most Z bracket for nutplates. As you may know, the inboard bracket doesn't get nutplates...they're on the spar instead. (I actully screwed this up on Saturday, that's why I quit for the night).
I'm sure it'd probably be ok, but 30 years from now I'll still be pissed if I don't redo it. I placed an order with Van's on Monday. Hopefully the new bracket (and a spare one) will get here soon.
