F18 is for a 65-amp alternator and J42 is floor pan dampener (insulation). The K in the VON (K63239) coupled with the 999 paint code almost certainly makes it a service vehicle of some type, but not police. Forest would make sense. Does that seem to be the original color?
Right on thanks for the info. Its been painted but it's almost identical to the original paint. As I pressure washed it some of the new paint blew off and exposed the original.
