1967 Buick GS Identification

Hey guys. Looking to see if anyone can break down this data plate & vin for me. I was told it's an original 4 speed car, but I'm always sceptical until proven otherwise. It's not a numbers matching car & has a 455 in it. There is no protecto plate & I believe the data plate is the only hope of proving it's a 4 speed. I know Buford24/Sean is great at identifying these data plates so I hope he will respond to this thread, but any & all info is greatly appreciated. Here is the pic of the data plate & vin.
Thanks
Josh
