Festival,
The fleet codes were important years ago as some people were trying establish pace car ID by "fleet code" as one of the primary method (s) of early identification. This was prior to the release of the real method(s) of Identification which included the now famous stripe delete - (dash) (which sometimes) was followed by a fleet code.
Owners who suspected they had a pace car were encouraged by the now defunct USCC and others keeping registry to make contact and register the specific car's information. Later as the respective total number of 0-1 and C-1 cars became known, the risk of being able to pull off a Pace Car fake was greatly reduced. The approximate build dates, sequences, and vin # then became known which protects the identity of real cars that are out there. As it is today the known use of the fleet code is much more consistant on the C-1 LOS cars as L-181A.
