OK, the number for the kit is 1327975, which consist of :
part number 133009p for the panel. Qty. 2
Number 1330097 for the fastener / clinch. Qty. 24

Number 305970p for the bridge, lower tail gate (incl. hinges, springs &
pins) D1 Qty. 1 screw, totail gateNo.6 x 1/2" length. Qty. 9
I am guessing that this is the piece that fits behind the front seat or a piece that is attached to the rear seat and flips up to enclose the rear area. Can't tell for sure by the pictures. Or since it is also available as a optional piece on the Ambulance this is more then likely a bridge covering the opening between the tail gate and the floor.

Number 2017x3 for molding, bridge board - rubber - 13-5/16". Qty. 2
As for pictures of what mine looks like , all I can tell you is that it appears that the panels have been welded inplace to cover the windows on ours. Won't know for sure until I strip the Body. Also there where no glass windows in place nor were there any windows there when the other guy bought it, but there are channels in witch they rode. There was no inside covering or insulation behind the the panels either when we bought it or the other guy bought it.. The picture of the panel in the manual appears to have 12 holes around the outside edge so it can be fastened to the body somehow. These may have been covered when someone did body work on the vehicle. Just don't know.
Well, that's my story and just about everything I know about the Panel Express Option. Hope that helps you.
