I try to take pictures of all the blades and any specific damage (if any) or other points of interest

Was used on many years

This part might possibly have superseded to future or previous years (1985 1986 1987 1988 1989 1990 1991 models) or past years as well

Found on both the Reverse lock assemblies that have inter-lock switches as well as those that did not
