Reps for Mitch at gearhead, he hooked me up with the speedo gear.
Apparently the gears that are 23 tooth are made a little smaller on the inside. I carefully took a deburring tool and using a 7/16 drill bit as a measuring tool, carefully (very carefully) worked out the inside of the gear so it was the same as the facotry ford piece.
It works like a champ, thanks again Mitch for knowing your stuff.
