Look at the JO counter shown at the heading of this page. The new counter (tentatively called "Jones Counter model JR") has the same mounting geometry.
Recent JO counters have a plastic gearbox. The geometry is different. It is not clear from your post which counter will not fit your bike.
Tom and I have not figured out how to make one counter fit every bike, so we elected to go with a geometry that fits most bikes.
