If this piece is cracked or brittle, serious water damage can occur. If you are planning to do a top installation yourself purchase any top WITH the rain rail your installation will go much smoother. If installation is to be done by a professional you can save money by using your existing rain rail if it is in good shape. The savings by not purchasing a rain rail needs to be weighed against the cost of a longer install time.
I think that Brian Goodwin is the perfect example of what is good about the aftermarket industry. He is one of the few vendors that actually cares about his customers. He is the example that all companies should be trying to emulate when it comes to customer service. Not to mention his ingenuity and desire to improve on what is already a great car. I have never had a "bad" experience with Good-win-racing. Well, except for the constant temptation to SPEND MORE MONEY.
Wow. That is really fast service on the shift knob. Thnx
