Landing gear.
I used 4-40 screws, so I drilled the gear using the indent marks on the base. Then I held the gear on the fuse in the position I wanted it and used the drill bit to make the fuse. I used a drill bit the size of the blind nuts to drill the fuse. Pulled in the blind nuts using a screw and big washer. Gear is mounted.
I had pictures of the tailwheel, but I can find them. All I had to do was drill a hole in the rear of the fuse for the main part to rest in, then 2 servo size screw holes for the mounting tab to screw down too.
