If anyone is curious, I picked up a very nice 1985 Nishiki road frameset to replace my damaged Fuji frame. The new frame is a higher-end model, maybe an International or Prestige, but I've no way to tell (it has a newer custom paint job, so no obvious logos or model name on it). It's also a 55cm frame instead of a 57, so it'll be a better fit once I get it built up.
