Bought a 72 Challenger, turns out it’s a 73!

As the title says, CA DMV shows it as a 72. I didn't know how to decode the vin and didn't notice it said 73 model year on the pass side emission label. Previous owner didn't know, I'm not blaming him. I discovered it when the seat covers for a 72 were very different. Took the seat back covers off and it was solid foam with no springs.
I guess I will have to go through it with the DMV. Does anyone have any front seat covers in black for a 73? I now have a brand new set of 72 front PUI...
