someone correct me if im wrong but ithink even corona may fit,i tried ma61 (SAME AS MY MX73) ON AN ST141? CORONA AND THE SPLINING WAS OK SO SHOULD FIT,ONLY THE DEPTH DIFFERED SLIGHTLY.HOPE THIS HELPS!ALSO I THINK MOST WHEELS USE ROUGHLY 87MM O/D BOSS SO MAYBE YOU CAN BUY CHEAPER BOSS AND DRILL AND TAP TO SUIT MOMO AS IM SURE MOMO BOSS IS OVERPRICED,YES?
