1940 Deluxe Coupe - Opera or What?

[columbussnake]

I'm doing a 1940 Ford Deluxe Coupe.
It has some jump seats, but they look jury rig.
I know that there was no real Ford Opera Coupe.
As I understand it, Ford called their Coupe with the package tray and no jump seats a "5-Window Coupe" ... and they called thier Coupe with jump seats a "Business Coupe."
I gotta replace some floor panels in the trunk area.
How can I tell what it was originally?
Any and all help here would be very much appreciated.

Thanks.
