I also remember them. Very sharp-looking on the Magnum, and attractive on the St. Regis, too. They probably helped with wind flow. I like how it looks as a hardtop. Interesting that it's value has risen so much. Perhaps because of its rarity, also because of its 327 V8 engine, which I think was available well into the 1960's in some Ramblers. The one I saw is a 4-door sedan, probably worth 4 figures.
