Your dealer should have the sheets of them, but the biggest one is probably only 3 or 4" high by maybe 12" wide. I did see some new ones at my dealer a week or so ago, and they looked bigger than what was previously available, but still not big enough to do a whole truck window. The one I have fits inside my sliding glass on my truck.

Always remember to be yourself. Unless you suck. Then pretend to be someone else.
