Kerry good call out on a 3 window. I think a solid Henry 3 window 32 - 34 body alone would surprise most folks here in terms of cost. Seems to me (somewhateducatedguess):
80% of them are on hot rods today
15% are on original well preserved cars (a very small subset) or restored cars
5%, if that many are more body remnants than bodies with a small subset of decent units in someone's garage, shop, etc. in varying conditions.
