30,000 miles got it on ebay

If you have the convertible you already have anti-flex bars...
With the anti-flex bars installed on my '95 with the targa off, I get no body squeaks and creeks cornering. I can jack the front of the car up and still pop the hood. They are expensive though. You better care about your car and plan on keeping it. Your not getting that money back.

You can see the bars poking out from under my car.
