I don't know if they are still available but it was possible to obtain replacement jaw and nuts sets for Jacobs chucks. .(Maybe similar for other makes?).
If not made now, unused sets might occasionally pop up among the second-hand tool dealers.
I'm glad you mentioned thar, I think I may actually have a set but had completely forgotten about them.
Now all I have to do is remember where I put them ~20+ years ago. Probably still hanging on a nail in garage (only problem with that, garage in Wales, I'm in Florida)
I won't ask my brother to look though, he'll probably sell them
