Installing Seat Belt Attach Assembly

I started today by raising up the fuselage on blocks so that I could get my angle drill underneath. I then proceeded to transfer the #40 holes through into the seat belt attach assembly from the fuselage floor. This would probably be easier with the fuselage upside down but in my limited space this seemed easier at the moment. I want all the holes in the bottom flange of the seat belt attach assembly in order to make drilling for the gusset plates easier.
