One other dimension I'd like if possible - the offset from the face of the flange to the block mating surface.
I'm assuming is is ~.61 from what I could find and the B/W drawing posted earlier.

I'm now making an offset metrology plate (blue) and one plug(red) for the crank adapter from JVX with the same .697
diameter as the input shaft.

using a straight edge from the crank flange to the bell mounting surface in several places, i got 0.600 [six hundred thousandths]

Awesome, thanks.
I was just estimating from the brewersperformance drawing, scaled to the dimensions there, so .610 was not bad.
