Massey Ferguson 245 crank pulley

[Dave131954]

Does anyone know where I can find the measurements for the 3 bolt holes in the crankshaft pulley. I need to make a plate to drive a hydraulic pump. Really a tight spot to measure. Tractor is a 1979 MF 245

The part number for the crankshaft drive coupling is 704812M93 according to the parts book. This site sells them complete with the cushioning bushings in them for the attaching bolts (3/8"-16 x 1-1/4"). It is threaded 3/4 left hand thread for the shaft. I believe the site has the shaft as well.
