In 1984, the CHP order was produced by Ford in two batches. The first batch was part of a 136-car group of consecutive VINs (V8 notchbacks), and the second group was 131 cars. Given that the reported number of 1984 CHP Mustangs was 250, then the two groups have more than just the CHP cars in them. Your car was part of that first batch, btw.
