Fidget, When I originally added these Photos, I didn't know how to make them large, now I do. The photo of the top 4 cars from the "base" Fairlane Series is from the original Sales Brochure that was printed in late 1957 illustrating the cars available for the 1958 models year. Some months after the release of the 1958 Fords, Ford Motor Company decided to add additional Chrome Trim on the sides, as illustrated in the Revised Sales Brochure for the "base" 1958 Ford Fairlanes. There does not appear to be any changes in Trim on the Fairlane 500 models, just the "base" Fairlane Series. It includes the three "rectangular" Trim Pieces on the rear quarters, as is evident in these illustrations.
