Need help assessing this 1965 Dodge Dart 270 4-dr sedan

And since nobody else mentioned this, you need to inspect every square inch you can see especially underneath for rust-rust-rust. It is your enemy and can turn what looks like a pretty decent car into a pile of junk if you get caught unaware.
The undercarriage seems to be solid, but I will remove the spare as JDMopar suggested and looksee!
