When I needed to CMM something I ended up putting it on an old shipping crate in one of the laser cutters about to be shipped at work and used the machine vision system to locate the center of each feature. Got me within about a tenth of a thou on each one.

You're also helped by the fact that the designers likely worked in even increments of millimeters, or half-mm's, so if you come up with 88.4683286, you can be reasonably confident its 88.5.
