That wear looks like the rods where not machine correctly at the bearing tang sides, the rod bearing tangs bearing side is sticking out (not completely round) far enough to make them wear
I had one Oliver Hemi rod like that, the bearing tang slot was too narrow to allow the rod bearing to seat properly
They, Oliver, paid to have it ship back to them over night by Fed Ex Express and fixed it the next day and shipped it back to me that night by Fed Ex Express Twod ay turn around
