Received the answer about the gap between WD-1207 & WD-1208; "Joeri, that has come up before. what you will need to do is make some shims that will fit into those spots. You should put a shim on both sides to keep the horn in the center position.
Van's" For that I fabricated the 4 shims from .032 alclad, match drilled #30 them with the control horns, clecoed all together and final drilled #12. Very nice fit with the shims.
