I knows its now probably a bit to late, but all that can be worked out with a vernier. It's basic geometry, You need a vernier, dividers, a decent 6 inch rule and paper and pencil.

I would have used a pair of calipers and a bit of 1/2" hss[I use 1/2 hss for all sorts of things].
Eyeball the things and decide if the boss is concentric and the bolt are symetrical, you can check with a screw and caliper if your not sure.
Measure: The boss diam, the screw diam, the hss thickness.
Put the two screws in the threaded holes.
drop the hss on top of the screws.
Measure across the boss and hss.
Measure across the two screws.
Now you can work out how far apart the screws are and how far a line between the two screws and the centre of the boss is.
Arghh Sergei. Simples.
same sort of thing, I would use my square across the screws and measure to
the boss at the sides to find out the offset. Or you could measure across each screw and boss with the calipers.
Think about what dimension you need and you should be able to think of a way to measure them.
