Measure the Outside Diameter chordal distance across those adjacent screws. Measure carefully for the greatest distance, and deduct the diameter of the screw from that distance. This is the radius of the circle the holes are located on. Measure the centering boss on the motor. You will need this to determine what size drill to use to ensure motor centering. Simple trig from there to locate every other, or the six, hole locations. You only need the dimensions for three. PM me with your dimensions.
PS: They are metric screws. We found 2.6 x .45 diameter/pitch work really well. Be careful of length, as too long a screw will hit the magnets or armature inside the motor.

This is a good measurement method. Thanks for laying it out. Interesting on the screws. I didn't even know there was such a thing as an M2.6 screw. I just stuck M2.5s in there, and I will say they did seem a tad loose. Hrrmm, learn somethin new every day.
