The ZL1 Camaros used a COPO number . . . NOT an RPO code. You can easily see this on the paperwork provided.
So tell me . . . what does RPO stand for? Does it stand for Regular Production Order?
It's the same thing with the 427 Camaros and Chevelles. Nowhere does L72 appear on the paperwork. Only a COPO number.

No - RPO codes get reused, so it is important to use contemporaneous references when decoding the RPO, rather than generic modern lists* which can create additional confusion. I think we can disregard ZL1 as a "noise control" device for the purpose of our discussion.
RPO = "Regular Production Option". In addition to RPOs there are also SEOs ("Specialty Equipment Options"), which can be used for low volume fleet builds. Uhaul paint schemes, hand throttles, hour meters, weird tires, etc, could all be defined by SEOs.
