Riveted the F-1015A-L/R and F-1018-L/R ribs to the rear spar bulkhead assembly.  Easy access on this side:

Tight fit for bucking on the forward side in between the two ribs:

Riveted the remaining ribs to the rear spar bulkhead.  Was able to squeeze the upper and lower two rivets, had to buck the middle three.  Squeezing the rivets:

Tight fit once you get to the middle two ribs:

All ribs riveted:

Riveted the left and right seat rib subassemblies and the F-1017A-L/R ribs to the F-1034 fuselage bulkhead assembly.  Was able to squeeze all the rivets except for two on each of the outboard ribs.  A lot of structure riveted together today!  I’m really going to have to move the wings to hangar before long – gonna run out of room shortly:
