Were all 87-93 FHP SSP's "rear defroster delete" cars or did this vary?

I have seen a few pics online of FHP SSP's (specifically 87-93) and some are "rear defrost delete" (ie: rear glass is clear, no defroster grid lines).

Did the FHP order all of their SSP's as RDD vehicles, or was this dependant upon who was doing the ordering (Dept. and/or procurement/purchasing)?

I checked the online Restoration Guides for the FHP SSP's and do not see any mention about RDD SSP's in FL - and I have not come across any threads discussing this either (unless I missed some) ... so it peaked my curiousity as to whether this was standard across the board, or if some FHP SSP's did come w/ the defroster grids.

The right hand dash pod switch would also coincide w/ a RDD SSP as well, as there would not be any provision for the RD on that switch if the vehicle was truly a RDD vehicle.
