I know its a long shot but does anyone have a set of DiaCompe 510 (DC 510) centerpull calipers? They are for a worthy project, replacing Superbe sidepulls on a custom Greg Diamond sport tourer. If you run across a set, please grab them for me even if its months from now. Also, I'd prefer complete with roller pulley but levers not necessary.
