While I was going to college I used to pump gas at my brother's FINA station, he had a 56 Meteor (identical to the one pictured above), I thought it was neat the crown trim was also part of the headliner.
There were numerous body alterations being done, altered wheel base, body mods, front ends being narrowed, rain drip rails being removed etc. IIRC there was a magazine article at the time about things that were being done.
