1988 Single-source

1988 from the OSG wheel page, which prints both PH0 and PHO; the options list prints PHO and calls the design diamond honeycomb; black (19P) or gold (60P); the rparts list prints PH0 with the same wording

This page aggregates every documented appearance of PH0 in the Pontiac reference. Confidence and citations are shown per application — the same code can be better documented in one year than another.
