To the far left is a very rarely seen motion ad that
talks about power options for the SS427 as well as the Biscayne -- The "street racer special". This ad is the back page from a Motion Sales pamphlet from 1969 and was contributed by Tom Cahill.
Another interesting piece of information that most people are unaware of is that there were apparently plans to include a stripe package with the Z-24 option in 1968. In the full-size assembly manual there is a page detailing the correct application of these stripes. Dated 8-5-67, it also has a large "CANCELED" stamped on it. Click on the thumbnail above center to get a better look at this canceled item.
To the far right is shown one area of the 1968 dealers brochure that lists the SS427 option. This is the area I referred to earlier that describes the front fender ornaments as being "bright metal".
