I have a 2001 Boxster S that I purchased 3 months ago. It's my first Porsche. The center lexan wind deflector has been rattling. Took it out and I noticed that one of the upper clip latches has a piece of plastic broken off of it. The latches can be bought and replaced. My question...how do you remove the latch and how do you install a new one into the clear wind deflector. Thanks for any help.
