Steve,
Most of the wrenches of that type I've seen only have two arms or pins.
They are called "spanners". You can try making your own with a fairly
thick piece of aluminum or other metal. drill and tap two or 4 holes in
it where screws inserted through the holes would line up with the slots
in the nut.. You can grind the tips of the screws so that they fit
snugly into the nut.
Peace,
Pat
