Australian A-body, where is the fender tag/option tag supposed to be?

First of all, that's a beautiful engine compartment!

Secondly, thank you so much for the info! As you can see there is indeed a tag/sticker on the RH firewall of this car, but when I've glanced at it quickly in the past I thought it was a worn-out decal, it's that worn. I'll try to get a more detailed picture of it tonight/this evening in the hopes that some info may be gleaned from it.

You're a Good Man, sir!
