Measure across the top side of the ribs.

i though you would measure long ways i did and my 3.60 is 3.5in ?

The flange on each side on the pulley is approx. .2", so if you measure across the face of the pulley and it measure lets say 4.0" then you subtract 0.2" from each side, you have a 3.6" pulley.
