You won't need any adjustment. Adapter plate lines up just fine. I bored the holes in the adapter plate to 1" and used four Delrin bushings. If you notice the adapter plated bracket cut with offset that was to move my motor forward a little (Not necessary). The ricardo bracket isn't welded up in these pics but you get the idea.
Fran thought I was nuts for urethane mounting my drive train. Unless you want ultra smooth, quiet and you're OCD like me, it probably isn't necessary.
