Avy Shades are a great substitute for the empty sail panel.  I discovered about two years ago that I wanted a window in that empty hole.  Since then I came up with this design, and they seem to be doing well, so I decided to let everyone else try.  I have tried other colors and designs but limo tint seems to be the best thing to offer.  We have received nothing but 5 star reviews on Ebay for these.  They can fit into any year as long as you have the plastic side panels. Most of the 2013's are smooth paneled so you will not be able to install these.   You need to be able to take the plastic screws out to install them.  Please reference the Avy Shades Youtube video on how to install.  Avy Shades are a great substitute for Snug tops!!  If you have any questions please contact us at JMTDesign7@gmail.com
