Prof,
In reality that a tough question. Are you wanting it like the originals SC type, are you using the same angles, where are your measurements taken at, and so on.
Basic they were 1.5" dia and about 10 .75" vertical in height for the inside leg taken at vertical centerline or the bar top arc.
Wouldn't Midstates give you those dimensions consistent with their frame member locations, and anles for rear leg and how they attach them?
