In researching the various items at
www.hamtramck-historical.com, it appears that "Color Sweeps" were only on Newports and T&C Wagons. Being standard on the wagons.
On normal Newports, the Color Sweep was not on convertibles, but other body styles. It could be paired with the Two-Tone Paint option or available separately. In either Black or White, if separate or with a black or white top on two-tone cars.
Had to get into the "Confidential Salesman's Price List" and "Option Codes and
Confidential Pricing" items to find these things.
Only on Newports? The configuration of the side chrome trim was conducive to the Color Sweep. Seems that some Newports had a separate end piece of Chrome to end the color sweep's area at the rear? Was this only on non-Town Sedans or others with the f/r bumper reveal moldings? I don't recall, but remember seeing some that way. Might need to get into the '66 Chrysler Parts Book for more research?
Happy Holidays!
