Some guys are good at adding shims. New driver will help but some times not. If terribly bad, then the crank would have to come out and machined.

I fixed mine with JB Weld. Just clean the crank and driver spline real good with brake clean and put a little JB Weld on the crank and on the driver splines. Not to much to make a mess. Then slide the driver into place and let the JB Weld harden. I work my "B" and it works fine. If the time comes to remove the driver just heat it with a torch and it will come right off.

I have no investment or connection with this add in any way:

I would say that a quick fix is of no value. Now having said that I think you will find that the crack throws will also be out of round. If it were me I would find another good crank and replace. I wouldn't spend a ton at a machine shop. A better repair would be to weld the end of the shaft...build up and then grind back down with a flat file and recut the groves. You can use the engine running as a lathe....don't do a lot of welding at a time.
