i have this one. came with the car when i bought it. pritty sure they are up on eaby quite often.
works pritty good. had a problem with it ratteling awhile after i got the car. so i just used some sillicone adhesive/sealeant around the edges of the box and screw holes.
if i had money/time id buy/make a nice plexi glass one that sits flat back there but what can ya do
