I had hoped to install the last 3 ribs tonight, but it always goes slower than you think. Just getting everything set up and cleaned up takes time.
This time I had to do some work to the outboard rib, first. It gets a 6-xx rivet installed in the tooling hole, end a reinforcing plate gets installed.
Then I finally got to installing the next rib. This was one of the better ones I've done.
