SB Pulley Help Please

Brian do you know the depth and diameter of the pulley you need? I have a few water pump pulley's but have no idea what their off of. If you can give me the dimensions I'll measure the ones I have and see if any are correct. An easy way to measure them is to lay it down on a bench snout first then lay a straight piece of flat bar across it and measure the distance from the back of the pulley to the i.d. where it touches the water pump.
