To add to the confusion, here's one of the oddball Canadian SPIDs that used the Super terminology on the RPO description, but it was indeed a Cheyenne/CST.

The RPO is what matters and YE9s were what made a truck a Super.

AJ, do you recall what the RPO was for the CST you saw with Super badges? Some of them had BOTH the Z84 CST and YE9 Super RPOs listed and would indeed be a real Super, but I've never seen one with Z84 CST only that was an original Cheyenne Super. Lots of Super badges have been added over the last 40 years. Got any pics or stories behind the originality of the truck you're thinking of? Would be interesting if it was one you'd bought new, or you Dad perhaps, or whatever, that has a full history behind it. Thanks for sharing, there are all kinds of odd/unexplainable SPID goings on out there... Ha.
