69 barracuda; what's it worth?

It's originally a /6 car, not sure of trans. Currently has small block/4 speed setup in it. Carpet is stripped out, the rest of the interior is likely rough are gone. will need at least passenger front floor pan replaced, rails I'm told are solid, some bondo in body. The trunk floor looks to have some rust, but not rusted through, good wire brush clean up and coating would probably cure the issue.

I havent seen the car in person yet, just wanting a rough idea on what value to place on it if the only issues were what I've listed and the rest is solid. I'd think 700 decrease in price per frame rail needing replaced/repaired would be an OK place to be?
