They are all 3mm, but two are closer together. One set is the typical 25mm apart, the other two are 19mm apart. Kind of a PITA when mounting because it reduces mounting options if you want the wires a certain way. PDF diagram (for the 70mm, but they all are the same IIRC).
Yea, that is the reason i haven't already purchased the one for the Neu and just use it. The mounting hole i believe is stripped is one of the standard 25mm spacing, so a spacer plate would need to attach on the 19mm holes.
