That 2 3/4 measurement is from the sort of raised ridges on the head the tool is resting on in the photo to the center of the rod protrusion that sticks into the hole in the tool. Since the rod end is a bit past the head laying a piece of straight flat stock on the head to extend over and then measuring from the BOTTOM of the flat stock with a small engineer scale is probably the simplest. Ross had another way which he posted but I just don't remember it.

All the tools were the PU-364-?? but they made some revisions over the years and changed the suffix accordingly. Early on the height of LHD hole from base was changed, added notch to base, modifying the angle of holes to base slightly so the tool rested with less interference on the head, the 359 head hole, the RHD hole, and tools with combinations of the changes had a different suffix.
