Answer:
I'm not sure about the page numbers, specifically, but I can give you a few examples of violence in the book to give you an idea of where in the book to look :)
Explanation:
When Ponyboy is jumped by the Soc's in the very beginning of the book, (just a few pages in), the several rumbles initiated by the gang, when Johnny and Ponyboy are getting beat up in the park, when Johnny kills the Soc, the rumble the gang goes to for Johnny after he dies in the hospital, when Dally is shot by the cops, and that's all I remember, though I'm sure there is more :)
I hope this helped though!!
