Appendix: The Body Plate

The body plate was GM's first attempt at providing service personnel with a method of positively identifing a vehicle, it's color scheme and the options it was equipped with to insure the correct replacement parts were ordered and installed.

Although effectively replaced in 1985 with the Service Parts Identification Decal (SPID), it can still be found in use on many G bodies through 1988.
