Can anyone confirm if all Cudas received insulation at the cardboard trunk divider?
Was this an option with some group or perhaps a model like the Gran Coupe?
What side would it have gone on? (trunk or cabin side)
Or is this something restorers do to make up for a factory deficiency?

I'm asking because both mine and another AAR didn't have any sign of insulation but it sure seems like this would have been done, particularly when one considers the insulation on the package tray.

Thanks for the help.
