If you are using the Hurst 6-speed shifter with the stock arm and white shift knob and are experiencing a "rattle", Hurst has issued a "fix" in the form of 2 isolators. We have been sending these to customers for a few months, but wanted to make sure everyone was aware of the potential problem and received the solution. We have plenty of the isolators in stock here, so if you need some, just send me a PM with your name and address and we'll mail some to you at no charge ... even if you didn't purchase the Hurst shifter from us. Thanks, Lisa.
