ya, at first i had a standard piece of plexiglss but i broke it in a week or two, so i got a 1/4 piece of lexan for$60 and cut it with my angle grinder, finished the edges, trimmed the bottom with a 1/4 piece of alum. u-channel. it fit in the weather stripping really nice and tight and then i drilled a hole on ea. side about 1/2 way up the top and about 1/2 in in from the window and used two small (1/4in) clevis style pins to secure it. it works great and comes in and out easy, but i can't open the tailgate from the outside. i am about to cut a 14 x 12 in hole out of it so my 38" spare can stick out fo it as it will be mounted to my cage at bedrail hight sitting flat behind my rear seat. ill need some sort of brush weather stripping for that.
