Empennage, Elevator (Part 14)

I didn't make tremendous progress tonight, but at least another small step forward.  I started work by clecoing the E-1008B Ribs (1/2 of a complete Rib) and E-1022 Shear Clips to the left and right Rear Spars.  Once clecoed together, I used the pneumatic squeezer to set the AN470AD4-4 universal rivets.  Below is the completed left Rear Spar with six Ribs and two Shear Clips.  The Elevator Trim Tab will eventually get installed on this Rear Spar.   
Here is a close up of two of the Ribs riveted to the Rear Spar.

After all the Ribs and Shear Clips were riveted, the right Rear Spar also received an E-921 Gusset.  The Gusset is pictured in the photo below.
