These are from my '84.
Kinda hard to get a front/back location shown in the last pic since the door isn't square and the edges are radiused. Going from the top, the holes are lined up about 1/2" ahead of the centerline of the button.
You could prolly be off quite a bit on that dimension. I don't think their front/back location is that critical.
