not to sound like a jerk, but if you have a hub you can make these.  you can figure out the measurments yourself.  not that hard.  you can see they have a step for little bolts to mount and just have to bore the inside out to clear the nut and cotterpin.  not to hard if someone has some skill and a lathe.  if i'm not doing anything tomorrow and with the storm, still have power, i'll make 2.  if anything i'll put them on mine.
