I took a closer look and some measurements of the dimpled drill points.
The dimples on the door are definitely right, the dimensions line up fine with the rubber bellows.
The marks on the cab are a little weird. There's four holes, and the two outer ones do line up with the rivet holes in the door boot. The two inner holes seem to be spaced evenly between them. Not sure why there would be 4 holes? unless it's because the cab wire hole is larger and they had some special way of cutting it?
Here's the door:
Here's the cab:
Do the cab dimples look like what you've seen before?
