Yes. Unfortunately the plywood construction in the wing gear mount area is not a "drop in" fit with the CARF supplied gear. Mine was not symmetrical either. So to elaborate on what Marty said:
You have to position the gear symmetrically then grind away enough wing skin for bolt head access, after drilling you will have to grind away some of the plywood support where it interferes with the blind nuts below the gear mounting plates. I used a dremel large fiber cutoff wheel for this. You will have to cut away some of the blind nut flanges also. Then install the blind nuts (and cut down bolts at an angle for the outer bolts} and tighten as best you can. Grease up the bolt and use a bit of epoxy here to fill the gaps produced by that angle. When positioning the gear make sure to approximate the toe in angle and take care that the tires do not touch the wing skins going in and out, the wheel wells are huge but the mounting plates will have the gear very close to the edge when operating! I also had to grind away some of the wing skin foam to relieve the gear air line fitting, it is that or shims but if you go with shims ensure the gear axle bolt will not interfere with the inner gears door closing. The main gear inner doors were also a challenge. I did it with all the supplied parts but I had to shim the hinges where they mount to the door to move the wire hinge away from the door a bit to allow for the wing skin thickness. I spent days working on the main gear and doors. But it works fine in the end.
