    Hey there Racer Girl!
    The POLR uses the same crank as a regular PO. Fairly easy to get and I’m sure I have an extra.
    Does he need an entire 4-60 or just the crank? If it is a crank, are you sure it is a true 4-60? Because the P-500 pump is different. The Storm Boat and Big Four are the same but different again from a pump or 4-60. The later ones are a little easier to find.
    What is wrong with the crank? As sometimes we just have it ground down on the pins and use oversize rollers. The other option is to have the journals welded and re-ground. Had not have to do this in years but had a good place in California who did that work if still in business.
    A possible solution too is to use a pump or Big Four crank with their center main. But they don’t have the point cam ground on the crank, it was on the flywheel. So no easy fix but fixable in one way or another.
