How to scrap a car?

I have a 70 Dart that I've picked through, and now I'm ready to scrap. The car has all panels, but is very rusty. it has the full interior minus the front bench seat (actually, I'll most likely just toss that back in the car to be scrapped as well). It also still hs the entire /6 drivetrain minus the tranny. No front bumper or grille, and no glass.

Is it worth me renting a trailer to take this to a scrap yard with current scrap prices? Or should I just call someone to come pick it up for free and call it a wash?

I've never scrapped a car before, and don't know if I can make some $ on it or just be happy to not have to pay someone to take it.
