-For some reason the counter-bored holes at the base are tapped. I drilled them out to make an M4 bolt slide through.

+  * #14 (0.182") drill to match existing holes

-There are feedthroughs to allow unbolting a lower stage without unbolting the upper stage (ie the bottom stage on an XY stage)

 Looks to be 63 mm bolt spacing
+Looks like you need at least 0.15" clearance from bolt shoulder to top. I observed that 0.155 bolts were getting scraped, 0.150 seemed fine. To be safe, I turned bolt tops down to < 0.13. This was done by holding bolts in a drill while using a Dremel cutting wheel to sand them down.
