School me on 68 dart parts

So heres my plan, I joined this site to learn what to look for when buying a Dart . Whats hard to find, whats not . etc.
What to look for when searching out the father/son project.
I don't mind a long term project or some rust repair . Budget will be a factor.
I know enough to find the nicest possible and go from there.
Just hoping for some insite and friendly tips .
thanks in advance
