Bronze distributor shaft gear wear

I agree it looks like it needed to be shimmed up, but that is likely because of the wear on the bottom face of the gear. I have a new gear, but need to get a new shaft too- don't want to use this shaft with the wear marks on it where it goes into the bushing. I have a hard time believing worn bronze particles scored the shaft like that. I think maybe it was an old shaft. Anyone replaced the bushing while the intake was on? If so, what tool did you use to take it out? I'm believing if the gear is correctly meeting the middle of the cam gear wear would be minimal.....
