Ben,

Following is a photograph of the serial number pad, which is in front of the distributor and just behind the crankcase vent tube connected to the valve lifter cover. There is no serial number on the pad and it wasn't until I enlarged the photo when I got home that I saw the following number stamped on the crankcase below the serial number pad - RE-057135. I did not have time to remove the water pump to get the serial number
