I added the dowels into the gun mounts. These dowels capture the 2-56 mounting screws which hold the gun mounts to the fuselage. Now I need to add the 2-56 blind nuts to the inside of the fuse. The rear mounting screw locations are going to be easy, the front two not so much. The holes are already made in the fuse so all the tough stuff is done.
Once the blind nuts are in I'll do the final shaping of the mounts.
