Pull the spindle to ensure the freehub body can be removed. On earlier Uniglide hubs, the 10mm allen sleeve may be absent; it could be rivetted on instead. In which case I wouldn't bother with the hub.
If it's replaceable, you can swap it for a 7spd Hyperglide unit or an 8/9/10spd one. Reasons for sticking with 7spd include 126mm OLD frame, more reliable indexing, and compatibility with Campy 8spd shifters/derailleur.
