Placed a blob of RTV silicone midway between the aft end of the F-836-L-1 and R-1 floor ribs Clecoed the F-850-1 bottom skin in place on the bottom of the forward fuselage Riveted the F-850-1 bottom skin to the F-836-L-1 and R-1 floor ribs. I used a piece of green dense foam on a paint stir stick which worked very well. Later i discovered that a piece of silicone sheet rolled loosely worked even better.
