I’m with Big John on this one. Until the condition of the framework is settled it’ll be a wildcard as to its future.
That being said it looks no worse than the shape my 65 polara was in when I dragged it home. I made door panels my upholstery buddy helped me with the seats and I drove it daily in Phoenix with no top. The birdcage worked so I just stowed it and I had covered parking at home and at work. What if it starts raining??? Just speed up a bit and try to hit all the lights LoL!!!
I’d drive it until I found a two door donor car and swap everything. You already have the hens teeth back seat and that’s the hardest part to find.
It does mine too, but sometimes it's hard not to consider it.
There's a car that's getting a little press right now as a very rare piece and I've been told there's very good reason to suspect the VIN tag was jacked up and another car was driven under it... I won't say who or what, but it's a fairly recent... ummmm... build.
This car is rare because its a 4 speed mopar that has been sitting derelict but it still has the motor and trans unlike all the other derelicts.
I say it is with in reason for the average guy if he is a focused one project guy. The best money spent would be on a real decent donor. Painfully maybe, even a nice turn key driver. At the end of the project it's not that much money compared to years and endless hours of chasing endless stuff. Something with a good interior would jump that project way forward.
You will be left with the skeleton of what was once a good car but really that's what you have now. I would rather see a run of the mill car sitting than that car. Either way. We don't know where you are in the cost. But if your in ok, its money in a savings.
With that low of production numbers there are people out there that will take it on.
The kicker is that it is a factory 4 speed convertible. All else is secondary. It will cost the same to restore as any other similar car, but, "when the top goes done-the value goes up". Still a labor of love.
The body looks decent without seeing what's underneath. Floor pans can come out of most C body's of the era and even reproduction B body pans can be made to work. Do most of the work yourself and you may break even. beats a savings account.
