Re-install: F16-03 Aft Tunnel Web Assembly F16-07 x 2 Shear Plate F16-08 x 2 Side Clip F14-09 L&R Aft Wing Attach Angle L04-02 L&R Tri-Gear Main Gear Mount Fitting L04-03 x 2 Spacer Cleco all. Cover Tri-Gear Main gear holes in lower fuselage skin with .025 sheet metal. I have decided to build the tail dragger version, but I had already drilled the Tri-Gear Main Gear Mount Fittings and cut the gear holes, so I went ahead and installed the mounts. If I ever decide to switch to the Tri-Gear version, I only have to remove the sheet metal covering the gear holes.
