For future reference, you can buy the shift lever assembly separately. At some point Campagnolo seems to have moved away from selling each individual spring, gear, and bushing (though those are still available for older generations of their shifters). Here's a source:

It looks like the replacement assembly for those Veloce levers would run about $72, which isn't such a great deal when you can buy a new set for $85, but it turns out you could actually upgrade to a Record shift assembly for about $97. I did this recently with an old Centaur lever. You may have seen my thread about the mismatch. It nags at my OCD, but the shifting performance is worth it.



(Note: For some generations there is a bit of debate whether there was actually a mechanical difference between different levels of shifters in the Campy lineup. In my case, I went from a worn out 9-speed Ergopower shifter to a NIB 10-speed Ultra shifter, so naming aside it was a definite upgrade.)
