Targa top adjust
Take off your top and put it in the trunk. Take a pencil and mark the top of the striker at the sides because to loosen, you will be pushing this up ever so slightly. My choice is to be too tight rather than too loose. I hunted for a hard to find rattle for about a year, thinking FOR SURE that it was in the center dash area. I finally discovered it was the passenger side targa striker latch. It felt pretty firm to the touch, but it was rattling badly at every stiff bump.
Back to the procedure- loosen the two 10mm bolts that hold the striker in place, and move up to loosen, down to tighten. You can see the bolts thru a slot at the top of the windshield frame. Just move it ever so slightly like a 1 mm if possible and try that then tighten. DO NOT OVER TIGHTEN THESE BOLTS! Light torque will do it because they have chanelled mating surfaces for better grip, but I think the windshield frame may be aluminum so it can't take too much twist.
Good Luck!
