The TA or Stronglight cups are thinner than Nuevo Record cups, typically about 2mm. This will alter the chainline and probably not leave enough threads on the lockring. Use the Campy cups or Sugino Mighty.
There will not be damage to the bearing surfaces if you can jigger it so the chainlines etc. work For example Stronglight and TA more or less interchange with older Campagnolo Record cups.
> I recently purchased a '75 Teledyne Titan BB titanium axle that is 68 x 120 and fully campy compatible.
> Question: Can I safely use a Campy 68SS-120 axle (pre-1979) with T.A. BB cups and the correct size ball bearings and not damage the axle & cups? The axles I have appear similar... I am assembling a vintage "weight weenie" Teledyne Titan and would like to put French parts (TA & Huret Jubilee) on
