72 valiant

I am lookin at purchasing a 72 valiant and it will be my first mopar. I was just wondering if there a readily avalible parts for these cars. the body is straight but it could really use all new interior. Also someone told me it was just like a dart. Can a dart replica be built out of the valient? If so what are the things that would need to be changed? Thanks, I hope someone can help me because Im Mopar stupid, lol.
