Remove port rudder hardware, make some changes and use the same brackets to install the starboard rudder hardware clickbonds.
Tape up the port clickbond threads and slap on 2 x BID reinforcement. (I think 1 x BID would have been enough). Peel ply over. I was going to bolt on the left rudder hardware to hold it flat, but I don't have enough non-aviation nuts. Push some taped mudguard washers over the result, and keep them flat as they cure.
