Took another look at the rear attach plate and still wasn’t happy with it so I redid it.Took only 45 minutes this time. Sailed right through it. I drilled all the rivets out of the other one, cleaned up all the holes, backdrilled the holes in the new part, deburred primed and reriveted it in place. Looks good.
Primed front attach angles and then started pre-assembling center ribs to spars. got 80% done with the preassembly.
