What was the original finish on the Cub wheels? In the protected areas, front and back side, it looks like yellow zinc chromate. The detachable ring on the front has a very light green cast like anodizing. Also, the brake drums need to come off for cadium refinishing; how easy is it to get the drums off and re-riveted correctly? If I mark the drums and wheels where the drums will go back in the same position, will they need turning like the new replacements? Thanks so much....................Will42
