I own a 1959 Ford retractable hardtop and have a copy of the full Ford parts books (1949-1959).
Under the bumper section it only shows the 57 Wagon/Sedan Delivery/Ranchero with a bumper and bumper guards (with the license plate lamps mounted in the guards). The low line Fords have a smaller bumper with the license plate mounted on the body and lamp as part of the plate holder. The Fairlane 500 bumpers are much bigger and have the license in a bumper recess with lamps mounted in the side of the bumper recess.
I suppose it could have been possible to get a different bumper on the Wagons with some other configuration of license/lamps and not guards via the dealer.
They got rid of this foolishness in 1959 and had one bumper/license/lamps for all cars (except TBird, of course).
I own a 1960 Lincoln convertible and it truly is a big car (but surprising easy to drive). There are longer cars (Cadillac and Lincolns from the 70's with 5 mph bumpers). But the 58-60 Lincolns are by far the biggest unit body cars ever made.
I've attached a few pixs of a car I built a few years ago. It's done in an unusual color and features cloth insert upholstery. I got the scheme from a online registry for these cars and looked until I could find one with cloth (and not black, white or silver.) I don't remember the site but I'm sure it can be googled.
I can't seem to get a picture to attach here but there was a long series of detailing truck engines and such from one of the 70s car model mags (Tidewater Trucker or something like that). Air compressors were addressed and there were both water and cooling lines to the thing.
The info was downloaded from some model trucker site where he had images of countless model truck pages. Perhaps someone on this board can point you in the right direction as I can't seem to find the links....
