I got all of my parts from Rennspeed motorsports in Arcadia. The guys name is Peter and he has always come through for me with a great price and a great part. In fact, I have seen threads on him in here and other forums. Usually his site works but right now it is down. Here is the link anyway. I will look around and see if I can find his number.
