Value of a 1972 Dodge Dart Swinger

Thank you guys for all the info. He sent me a photobucket link with more pictures, but I do not see a fender tag in them. I wrote him asking if it has one that I can not see...one pic looks like you can see the corner of one.

Now to help my knowlege on these cars...

Lets say it had the fender tag and everything else was the same. Drum car, original 225 now with a 318, etc... What would it be worth? I have been going over the classifieds and I see prices all over...depending on what they are of course. So please based on your knowledge what would a car like that go for?

Thanks again for all the great info...Keep it coming...
