Thinking about sellin my 75 Duster 360 but not sure what to ask.

Thats the problem im not sure about how much its worth ive seen just bodies like mine sell for $1500. The engine im not sure what its worth havnt been inside to get brands off of the internals just pulled plugs and got a led inside it. Im personally just looking to break even and i would be happy. I have pics in my gallery of it while i was doing work to it and all.
