Right side door mirror locate

[Too Many Projects]

I need a reference for the holes to mount the right side door mirror. I thought I had an assembly manual, but haven't seen/found it since the move 3+ yrs ago.

The door had a mirror at some point in it's past, but it did not come from the factory, as there is no reinforcement plate inside. I will make a plate, but would like to know if the existing holes are in the correct location.
Measuring from the front of the door, the front hole is ~ 9.25 back with ~ 3.5 width to the back hole. Unfortunately, the holes are not parallel from the top edge down, so I will be moving one, if not both of the locations. Front hole is ~ 1 1/16" from top edge and the is rear is 7/8".

If someone has a manual with the specs that could post a pic, I would greatly appreciate it.

Thanks SYC
