Quote from the novel "the outsiders" telling decade?

Question

What is a direct quote from the novel "The Outsiders" that proves the decade they are in ? (school project)

Answer 1

Oh geez I don't have the book with me but I do remember that they talked about sneeking into drive-in movies and they used typewriters. unless I'm confusing this book with "Ponyboy" which was by the same author.

So just search for something like that.
