Well... Its realy not that hard to be honest I just attacked mine and took it off its held down by alot of silicone and three screws. I used the original rubber washer seal things, used superglue to hold them against the glass and then used these three plugs I found on the floor of my garage! Luckyy find those, I tried silicone at first but it refused to stuck onto the small adhesive area of the window and was realy messy. I've checked the car after rain for moisture for the last 6 months and nothing at all, it works realy well.

KI11z is right on the money there, they look fantastic for such a small amount of work. And the best thing is... its cheap doesn't cost you a cent well maybe a few hundrend cents but thats all. Oh and If you've ever driven through a bucketing rainstorm with trucks stampeding behind and overtaking you, your gonna need a rear wiper. As good as it looks its realy neccesary for adequate road safety.

Check these out in the meantime:
