Looking For A Parts Catalog, Can You Help??

Thanks mike, i appreciate it, so i know that 74's will work in it, but will 75's work too? I went to a junkyard today and got one out of a rolled 77 but the clip that holds the spedometer cable snapped, as did the one in my car, so now i have to drive around and risk it popping out. I hope i can find one soon.
