Hey, I showed you a 1000 dakota already!
Part out the body and you could break even.
I know you are going to try it anyway, but fit the body on the whole frame before you start chopping. Seems that since the center of the old frame is gone, you would be better off.
If you have the short term cash, buying a nicer one might net you better than the rusty worn out hulk that needs full suspension. A shell should net a hundred or 2 alone. I see you are already advertising locally, good.

Another across the country.
