Clear turn signal lenses, urS4

[JMGarciaJr@aol.com]

OK...yesterday an errant pebble manages to bounce off the pavement at 70 mph 
off the back of a gravel truck and hit (and smash) my left turn signal lens. 
Great. At least now I have the opportunity to get clear turn signal lenses.

Question. Who carries these, what is their URL (or at least, phone #), how 
long does it take (i.e. are they in stock?)  and what does it cost?

Thanks!
