If it is a California car, it probably has the Clean Air Package, explaining the black air cleaner on the Commando engine. The 9 inch brakes all around with the disk brake master is odd, but possible. Weird things happen on the assembly line.
The vinyl top on the car is a rare option, not many had that. Whats the 7th digit of the VIN? If its a 5, the car was made in the Los Angeles assembly plant, confirming the mandatory Clean Air Package.
I would love to see a clear photo of the fender tag.
