Denso window motor mounting hole location

[2544HCRC]

Does anyone have a definitive measurement location for the window motor hole location. It seems that the single bottom hole is 1.825" off the center of the drive spline. The other 2 seem to be 1.825" above the center of the drive spline and 1.125" off the center line and not on a hole circle. It seems an odd araingement and twice now we have had to move holes with a grinder. Not unusual for us but I don't know if it's the holes or the hole placers. Are these metric? Is one of these holes off a bit? It's getting frustrating making plates and not having the holes in the right place.
