Jay: My apology. I just saw that you were asking about the 4/4 Sport, not M3W. I would need to know what the instrument locations are. I suspect something like a Walsall (Makers of the Les Leston wheels) might work well. Possibly even the Bluemel's design I posted above from TOK. The Walsall would fit your Moto-Lita boss with only some re-drilling of holes.
