1/18 Ford Crown Victoria Police Rear Door Cage. CONFIRMED: these window cages WILL fit the 1/18 Motormax Ford Explorer as well. The rear doors do not open on the Explorer, so disassembly of the model will be required for install. This listing is for a pair of rear window cages made for the 1/18 Scale Ford Crown Victoria/1/18 Scale Ford Explorer. Add the extra detail to your next police car model or build with realistic prisoner cages; found in many police transport vehicles to prevent damage to the rear door glass and potential escape of the prisoner. This includes the window cages only (photos 1 and 2) and requires re-use of factory door panels. Installation is easy-simply glue the window cages to the top of the door panel. Vehicle retains all factory door functions as well (Crown Vic). Removal of rear doors makes installation easier (Crown Vic), although it is not required. Detail instructions can be provided upon request. Cages are paintable if a different color is desired.
