That's what I was thinking, but the car was repainted so who knows.

It does have the divider tabs, the trim is just off the car.

I have the build sheet, it calls out "T" under top as well. I can't imagine such a plain car was ordered with a specific and odd top color? I know google isn't the end all of things, but I wasn't able to come up with another car this color combo.

I also have the original purchase order from the dealership, they traded in a 1963 Chevrolet "4 door Sedan" - Gussing Impala or one of the variants along with the original Pontiac Warranty fold out.

Would the PHS documents confirm if the top was painted or vinyl? I've never ordered one before, so I don't know how specific they go on the info they provide?
