My 2 cents...
Having looked at many different versions, I (IMHO) think the Factory Chrysler version is the best.
Look closely at the edges of the PLASTIC (vs LEXAN) that some show. Some look like they went to the hardware store and bought the material and cut it with a jigsaw.
The MOPAR version has radiused smooth edges and a nice center support channel that keeps it from deflecting/warping.
NO, I don't have one...
only because I like the breeze blowing my neck hair up on my bald head!!

PS: This should be in the Roadster Section. This Section is to post things significant to areas of the world such as GTGs and such.
