Glad my thread could help out! I went with the bolts and nuts because there is no way to bolt anything from the outside in... The holes in the stator core aren't threaded so there's nothing to bolt into to hold the stator to the plate if you bolt it from the outside in... The spacer cut from the original inner cover has threaded holes, so running a bolt from the backside of the stator core, screwed into the spacer, then the additional spacing washers (to push the stator inside the rotor more), through the new steel mounting plate, and then finish with loctite nut keeps everything nice and secure.
Let me know if that's unclear at all, or if I misunderstood your question....
