I have T600 but the motor fixing has 2 screws and not 4, did DJI issue the same V1 motor with 4 screw fixings and others with 2?

A snapshot may help to understand the issue ...

The original E800 - 3510 Inspire 1 motor had four threaded screw holes:


while the V2 motor was upgraded to the 3510H which only has two screw holes:

This is my motor, confused now ? V1 or V2, are the dimensions the same ?
