Fellow WW, need some help here:
Could someone take some measurements of the holes on a Speedplay specific (4-hole) shoe?
Working on a small project and I need to know the locations of the holes relative to each other, on center.
Metric dimensions preferred.
Thanks in advance!

I would do this if I had a set of accurate digital callipers to take the measurements for you. Unfortunately I only have rulers. If no one else has a more accurate way of doing this I would be happy to take some measurements tomorrow.

MM would be fine, so if you've got a ruler with metric that would work too!
I really appreciate this!

haven't got anything to measure true c-c, but i put some screws in, did o-o and subtracted diameter...
front holes 17.5mm c-c
rear holes 23.8mm c-c
front-rear 55.6mm c-c
the holes are symmetric wrt the front-rear centreline of the cleat plate
having said that, from a quick check with a ruler, i think their native dimensions are probably based on 1/16", so the respective lengths become
11/16"
15/16"
2 and 3/16"

Actually, Speedplay uses the Time TBT 4 bolt pattern, which is in metric units. Dimension of the Time/Speedplay bolt pattern (as well as all the other common bolt patterns) can be found in Sutherland's Handbook:
