I'm trying to figure out how to "properly" figure out the offset on my water pump pulley. Some one had said to flip it upside down on a flat table and measure from the table to the middle of each groove.

Also does any one have a pulley that may fit? or know some where I may be able to find it?
I need a 5 3/4" - 6" diameter pulley
Offset (using the above way of figuring out the offset)
1" from the table to the center of the first groove 1 5/8" from the table to the middle of the second groove.
