    Different mag plates would more than likely be attributed to where the throttle cam pickup is attached to the underside and such…By keeping the FD11 parts together, you mitigate most of the issues I would think.

    My guess would be bolt the whole later powerhead on, mag and all, so long as the recoil and cowl don’t interfere.. just my .02

    And I am no expert..
