Question for NYPD officers about a FCV RMP

[Oldsmobile]

Hello. I have a question for NYPD officers. In 2001-st year, Ford Crown Victoria RMP has a plastic backseat for a suspects? I know that FCV has a partition, but is it really has a special backseat or it was a original backseat from FCV?

P.S. Sorry for my bad english
And if somebody have a photos, where pictured a interior of the NYPD RMP, please post it here.
