Brian I have had the exact same thing happen with my balancer dude. Only I have found even the NOS 21A rods need resized. I have my own Sunnen rod hone and had sized and polished the rods before taking them to the balancer so I were super pissed. Fortunately he barely touched the polished surface. So I had to resize and repolish them. When I resize NOS rods and when I corrected these rods all I do is take the caps off and hand sand the mating surface on a piece of 180grit sticky that I have stuck to a flat machined surface. It takes very little and NOS rods can be as much as.0015” too big. After hand sanding very carefully and rotating cap end to end during sanding I now resize correctly the wrap 1600 grit wet and dry sand paper around the honing mandrel and polish bearing surface. It’s actually not that big of a deal and doesn’t take long. Hope the helps at least with the blood pressure. lol. Holler at me if you have any questions.
