What I heard, from a knowledgeable source, at Tulsa (Dave Grow) , regarding the springs' failure was due to their steel's high-carbon (for strength) content. Spring steel is reportedly more susceptable to failure-corrosion, than mild (body) steel. I don't know the chemical-content/reaction of Tulsa's groundwater, in the context of 50 year's exposure, but, the thing speaks for itself, that the body-mass, bearing down on the leaf springs (with the microscopic voids, between the leafs) in continual contact with water that had leached thru concrete, and Gunnite, did a "job" , on those leaf springs!!! Also, no one has yet mentioned the interesting fact, that the trunk-support-bracings corroded away from the trunk skin! Bet that nobody's seen THAT, either. What clearly occurred, was that the water that immersed the car got "into" the non-painted voids between the bracings and the under- trunk , and just sat there, maybe-never evaporating, until the bracings just collapsed away from the trunk skin.
