if anyone is interested, J C Whitney sells a window channel part that fits perfect in the rear side window (quarter window?) for the 1957 Fairlane 64B body style (two door post).  so far I have installed this in the top channel of my rear side windows.  I will post the exact part number and a pic or two if there is any interest... oh yeah, its quite affordable compared to some "specialty" parts suppliers out there...
lemme know.
