Some other comments:
Jim M is correct - the order codes / RPO's generated the broadcast sheets. Naming conventions were up to PR. This isn't conjecture, this is fact. I'm not sure what you want for proof on this. Did you read this: http://www.camaros.org/assemblyprocess.shtml?

If the RAIV engine package didn't include RA, then again you can have a RA engine but not have RA on the car.

Vikki,
Thanks on the VINs. I was really commenting on the ones with R/A on them. Be nice to know for sure what they are. I thought the first one could be 9U1114237. Anyone knows where the second one came from? It would be nice to even get part of the VIN to help pin down the dates.

And I haven't seen prices change that much on Chevy options. Normally they are stable unless something in the package changes. 348 prices seem to wander around. ?

I've seen errors in early publicity photos, but generally not in publicity text. Especially text that is repeated multiple times.

Also, the definition of insanity is doing the same thing again and again and expecting a different result.
I guess we're insane cause Jim isn't going to change his mind on this and he's insane cause he keeps posting the same pictures over again.
