I have that Golde Brochure S C H I E B E D A C H E R which clearly shows a 1957/8 Ford Fairlane with the WINDBAR!!!
The windbar along the front of the crome surround around the windscreen is thin and held in place by a support each end.
The photo i have is a clear colour shot, but with no digi cam i cant post it on here for you to see at the moment.
Out of interest the roof serial number was model 39 all steel sliding roof.
You could order the all steel sliding roof with a plexiglas insert, as used on the 1960 Pontiac range but that another story!.
Hope this answer your question John
