I would expect that someone like OPH would know;
the fact that him and Dennis both suggested that HF wheels are the originals, had me scratching my head.

GM was known for replacing one part with another, and my post was me thinking out loud, that maybe XE was the replacement (but it may have also had an earlier application).

I only have 67-76 Firebird, 77-81 Pontiac, 85-91 Grand Am, and 85-91 (Oldsmobile) Calais master parts catalogs - so I cannot reference any pre-1977 Pontiac parts which is not listed in the Firebird MPC.

Your reference describes "primed" XE wheels. I guess that makes sense for replacements but suggests any XE wheel has non-factory paint?
that's the wheel’s offset;
