Get a grip on your top. Under the front and rear edges of your Targa top, there are small clips that pull against tension bars on the windshield frame and Targa bar. Body flex eventually wears grooves in the tension bars. Our improved clips are wider and offer a more secure hold. Even if your bars already have grooves in them, our wider top clips will bridge the gap. 911 C2/4 owners: our improved clips are contoured better than your wide clips. Screws sold separately.
