I have a Challenger panel board and one of my breakers is no good. When I went to buy a new one they don't carry them anymore. They said they only carry the after-market ones. So I got that one, but it looks different than the original one. Will it fit in even though it's a different looking one?

You can use BRs instead of Cs
If your panel labeling says it takes type C breakers, then there's an easy way out of it: type BR breakers (as depicted below, with the type C labeling highlighted) are legal, safe, and widely-available (at any big-box or hardware store) replacements for type C breakers, as they are cross-listed (as per this letter from UL to Cutler-Hammer, as reproduced at the bottom of this post) and cross-labeled to replace type C breakers. (A more modern version of this letter is available, linked from an Eaton FAQ.)
For more exotic Challenger breaker types, Eaton cross-reference document TD01201041E provides the gory details.
