Those would be 7400/7403 front/rear hubs from the 8 speed days. The rear hub would have to be the 7403 UG/HG combination freehub body that could take 8, 9 or 10 speed cassettes. A Uniglide 8 could be fitted using the small threaded cog or Hyperglide 8, 9 or 10 speed cassettes with a modern type HG lockring.
