Dimpled and riveted the nutplates to the F-1015J scat tube support.  Dimpled the forward fuselage ribs. Began to rivet the WD-1004 nose gear tension fittings and F-1001E-L/R center angles to the forward fuselage ribs.  Could squeeze about ½ of them.  Will have to shoot the rest:

Getting pretty crowded!  Hopefully I’ll get the wings and the tailcone to the hangar in the next several weeks:
