Neil:

On my car (Kirkham) the motor mounts on top of the drivers side footbox with the first tubing section doing a very mild 90 degree bend from the motor to the first wiper box.

Also on my car, the centerline between each wiper shaft is 19 1/2 inches, and 1 1/2 inches out from the frame of the windshield. Your car is probably dimensionally different, but this measurement is probably a good place to start. Find centerline of your car and locate your holes 9 and 3/4 inches out from that, and with your windshield in place, measure 1 1/2 inches from the edge of the frame (not the rubber strip) to the center of the wiper box shaft hole. If, when your windshield is in place, the wiper box chrome bezel is just at the lip of your rubber windshield strip, your measurements should be spot on. If it is overlapped by the strip, move it toward the front of the car until it is as described above. Also remember that your wiper boxes pass through your body at an angle, so the edges of the holes, once cut, should be shaped to accommodate that angle.

Hope this helps.
