Also, here is what someone at Autobytel wrote:
The Dodge Scat Pack was originally introduced in 1968 with the Charger R/T, Coronet R/T, Dart GTS, and Super Bee. In order for a car to enter the Scat Pack it had to be capable of running the quarter mile in the 14s (14.99 or faster). Mainly a marketing term, Scat Pack cars got twin bumblebee stripes and special decals.

Scatpac Club was a Dodge promotion centered around their HP Dodge cars such as RTs, SuperBees GTS. When you bought one of those cars the dealer would send in your information. You would get a packet in the mail containing promotional info, a club certificate and two scatpack decals. The decals went on the quarter windows. Some dealers had packets available at their dealership to give to new owners when they purchased their cars. Contrary to some info out there the decals were not applied at the factory. If the dealer failed to submit your info I'm not sure if as an individual had to pay for a packet.

Here's a site that has a good depiction of the different decals. Unfortunately they can't sell the decals due to the FCA copyright infringement lawsuit.
