Marked, drilled and riveted the platenuts which hold the F-782C cover on the floor between the rudder pedals and riveted the platenuts into the firewall recess. Removed my short stubby temporary gear legs, cut the legs shorter on one of my saw horses and placed this underneath the fuselage main spar, so I can bolt on the main landing gear mounts. Bolted on the right and left side landing gear mount with bolts through the spar, torqued these and now just have to match drill the bottom holes through the side of the fuselage. Drilled out these 5 holes each side and the two holes each side which bolt the front extended piece through the fuselage. The two holes either side needed to be countersunk to take the AN509-10R12 screw, torqued all done.
