My understanding is that you were just looking to bore the two overarm holes. If there are three, that complicates things a bit, but the approach is the same.
This uses a vernier caliper and some telescoping gages.
Gotta do a little math. Not difficult.
The vernier tips do not have a not radius therefore I'm not sure that it is as accurate as I'd like.

This Sorenson Center Mike is my go-to center to center mic. (Yes, they call it a "Mike").
It somehow calculates the actual centers of the holes.
Note the directions.

...Just bought a 13" Sorenson...
I might be inclined to machine plugs out of some scrap material and leave a 1" diameter stub on the plugs. Put plugs in bores, measure outside to outside of the stubs and subtract 1".
Result is your center to center distance.
Daryl,BGHansen,
I've been facinated that it does the calculations without electronics!!
