Those Ram Air hood emblems are strange. There was a 68 RAII car in HPP a few years ago with those emblems (the emblems replaced the "400" script), and no one knew where they came from, even HPP stated they were a mystery.

Pontiac Parts Catalog lists (just after the OHC and 350 hood emblems) for 1969 F/8 (Firebird):

9796827 PLATE, hood name (Ram Air) - RH
9796828 PLATE, hood name (Ram Air) - LH

I realize that the term "PLATE" is not an emblem, but does anyone know what these part numbers are?

There was a theory that these emblems may have been produced by Pontiac as a retro-fit to those that bought a Ram Air kit over-the-counter for their 67-69 Birds. The term "Ram Air" was a status symbol back then, and announcing it on your hood was something special. You could take your "400" emblems off and apply Ram Air decals, but then you'd have holes where the "400" emblems were (unlike the GTO's hood), so the theory was that Pontiac made these to replace the 400 emblems as a retro-fit when someone bought a Ram Air kit over-the-counter.

Another theory : On the early 1969 Firebird 400HO's, you had to order the Ram Air Inlet option separately. Those that didn't order the Ram Air Inlet were most likely disappointed when they received their Firebird 400 with a standard air cleaner and closed scoops. If a buyer (or the dealer, trying to make nice) ordered a Ram Air kit for a customer's 1969, could these emblems have been used to replace the 400 hood emblems?

So there was the set on the 68 RAII car in HPP, the E-Bay emblems, and now this yellow 68 has them (although the guy with the yellow 68 obviously didn't know the emblems were supposed to replace the 400 emblems, not in addition to).

Any info would be appreciated. I've been looking for the true story behind these emblems for quite some time. Not trying to stir up anything, just trying to figure out where the heck these die-cast emblems came from.
