the ss, st, m and sc all use the "bearing in case" swingarm pivot. all are fundamentally interchangeable in that sense. so any 400, 600, 620, 695, 696, 750, 796, 800, 900, 1000 and 1100 engine from those models will fit the frame mounts and swingarm.
the hm, mts and the 916 on sbk use the "bearing in swingarm" pivot where the swingarm mounts are narrower, and the hole is lower in the sbk cases. not sure about the 2v re hole location vertical wise.
