Measurement on a 1518 from the front of the can to the lip of the wire grommet. Basically the spread for a motor mount. The distance in mm from farthest point on the can that a clamp will seat and the front of the motor.
The 1520 is 78mm, so assuming the 1520 is 74.5mm from the grommet to the nose, but want to be sure.
