Bill: I made some measurements on the crank pulley. Here's what I got:
clearance hole for M8x1.25 bolt = 0.308 inches
bolt hole center-to-center spacing = 1.832 inches ("A" on your drawing)
bolt center circle diameter = 2.585 inches
I'm going to lay it out on my steel plate tomorrow and drill it. Let you know if it fits.
