Hi Matt
The hubs that you pictured are early 90s chorus as opposed to record. The front hub was a carry over from the Croce d’aune groupset and is visibly different from the record one of the same era.

Hard to say wyhout seeing the spline but that looks like an Ultra-Drive cassette, which fits all Campag splines, according to this thread:

I've got a pair of C-Record era Chorus Exa-Drive 8-speed hubs in very nice condition, with smooth bearings and freehub. 36h front and 32h rear (this seems to have been a common setup at the time, no idea why). I have a complete c.1993 group and was planning to use the hubs to build an 8-speed bike on a yet-to-be-bought frame, but have an N+1 problem, so could be persuaded to part with them for a decent offer via PM.
