Wait. all is not lost. I compared the distance between bearing surfaces of the Berthet, the 45D, the 45A and the Atom 700. They are all very darned close to each other. So there is a good change the spindles will interchange. This is good news, since these pedals were made in huge numbers, so there have to be a lot of trashed potential spindle donors around. No guarantees, but I'd look for some trashed 45D's with the right pedal thread and wrench flats. This was the stock pedal on most early 70's PX-10's.
