Confused

[72superproject]

I purchased - what I believe to be a 1972 Cheyenne Super SWB over the weekend. The truck has all of the markings of a Cheyenne (inside wood grain, outside super markings, but the glove box has option n0. Z84 Cheyenne Equipment. The truck also looks to have factory air, PS and tilt, but no reference in the glove box - the truck is defiantly a 72 because the 5th digit is a 2. The other item that confuses me is the model description reads CE10734 - which researching on line shows to be a 1968 - The vin in the glove box matches the vehicle vin. Any clarification would be very helpful!
