As far as I'm aware, all A10 small journal cranks are the same. Don't see too much of a problem drilling a hole in the rod. Just make sure the hole is the correct diameter - not sure what it is off hand (let us not forget the work of Jean Louis Marie Poiseuille !) *eek*, and get the angle right. Or even simpler, just find a rod with a hole.....not too hard to find a good used one at an autojumble. Good luck....

It will fit. I am running a small journal crank out of an Ariel Huntmaster in my '55 Flash.
