Yes. The mount is designed for use with a 3/4" hole. The underside flange,
and the topside button fit a 3/4" hole.

If you have extra time, and you want a waterproof mount, once you tighten
the mount down, put a small bead of silicone down around the outside of the
mount, wait about 2 hours, then put the antenna on. If there's any
squeezeout, leave it to cure for 24 hours, then cut it with a razor knife,
being careful not to scratch the paint underneath.

I'm planning a drilling / punching project myself.

Q. What hole size tolerance is acceptable for an NMO mount, is 3/4 the only
allowable size?
