If anyone is installing the RX8 and went to install the adapter for the motor mount and need to get the tabs for Pro-4 to sit level no need to use the larger set of holes on the motor. The SCTE screw are 3mmx10
Solution
All you have to do it take the front end bell screws out, and rotate it. then when you have the desired hole size where you want it, screw it back together. my pro 4 has the leads right at the top.
Hope that helps anyone installing one for the first time.
