It's not a big deal. I'm happy with the part. Have full set of both, which is what I wanted. I'll sell the coupe pieces now. May also have been a weird switch at the factory. They are very similar. The only difference is the little tab on the end of the vert is about a 1/2" shorter than the coupe.
Honest dad, that 455 on the side of the block is a serial number
