Thanks!
I would certainly consider making more. ECI Hotrod Brakes has a plate that adapts a 4 bolt Ford to a 2 bolt Ford. http://ecihotrodbrakes.com/master_cylinder_systems.html It's about half way down the page.
The one I made adapts the 4 bolt Ford to a 2 bolt Chevrolet. I have modeled it with CAD and I have a friend who has a CNC mill so production can be pretty easy.
