were these steel races GLUED into the alloy cups in Athena HS? I know Campy used some sort of semi-rigid elastomer (SELFORM?) in some of the early 90's HS (such as Chorus) but not sure about the entire line or how long that practice was applied.

Edit: I can answer my own question: Athena did not get the SELFORM addition, only Croce d'Aune,C Record and Chorus were so blessed.
However, if there's a any looseness when you get this steel race pressed back (as a result from forcing it out accidently) you might get yourself some Loctite GREEN with "wicking" properties, then it would be glued in.
