Water pump pulley spacer

Going with a crank trigger sandwiched between the Crank Pulley and the Damper. The Wheel is 1/4" Thick. I already have 1/4" of washers for spacers behind the Water Pump Pully so the 1/2" Spacer I posted up should hopefully get them to line up perfect. Using Electric Fans on this set up so No other spacers will be used on the front side.
