I bought a 1993 C-4 Coup LT1 the Targa Top is warped from the sun and I need to get a replacement or this one refurbished the Issue is as I drive down the road the top rattles in the two mount pins in the back of top is this the wrong top or will the top be ok with new lexan or Carbon fiber ??? can I replace the pins with correct one if that is the issue ?
