With it sitting on the ground, one would have to wonder what condition that frame is in.

A 57 was the first year for the torsion bar suspension and the car had a full frame. My son has a 57 wagon like that car with a modern hemi in it. We stripped out his parts cars a few years ago. That one looks pretty complete and may be a great starting point, There are a lot of parts on those cars that are hard to come by that appear to be present on this one. Many things (like replacement windshield gaskets) are crap and pricy, they don't fit well at all.

For whatever its worth, my son loves his 57 wagon, not many are roaming the streets.
