Howdy all
I got a euro spec wind deflector (windschott) for my cabrio.
Our US version does not have the upper attachments.
You can use the following ($1.99) for attachment.
Harbor Freight Tools - Quality Tools at the Lowest Prices
Loop the non-ball end through the upper (as shown in an earlier pic)
Then over the rear of the roll bar and down to hook with the deflector's lower attachment loops.
See the following for detailed pics.
