Hmm, a small update: apparently police model CVs from February 1992 were [P71]s (at least, that's what I've found floating around online)

could this mean there needs to be a mass reclassification? (ford man had said all 1992s remained P72s, which had been a hold over from the 1991 model year, since it seems from 1983-1991 all LTD Crown Victoria's that were taxi or police models were P72s)
