when boneyard shopping the other day, i saw a hatchback like mine with what looked like a factory rear window louver... kinda like some older celicas had. were they ever an option, or was this off something else? i am thinking about going back after it. it needs to be painted, and a couple of pieces of mounting hardware, but i think i could stodge it together. i think it would look kind of sweet if it was painted up. i'll have to remove my rear wiper, or at least disable it. anyone have one on their HB and if so, do they like it or not?
