RCM revo motor mount + Neu motor question

The rear suport on the revo mount is made for feigao smooth or finned can, and the Neu finned can is larger than Feigao, so it's impossible that anyone of the both rear support fit.

I've tried of many way to fit it but nothing to do. The motor is bolt right at his place and the smaler rear support slot don't align with the 2 holes in the motor mount.

I realy don't know how you can fit the rear suport with the Neu finned motor, but something should "pryied" very badly

Plus, the half moon shape in the rear mount realy don't match the motor can shape.
