I always felt the clunk was coming from the rear end. Too much backlash in the ring & pinion IMHO. But it could also just be the combined "slack" in the clutch, transmission, driveshaft and ring & pinion. I'd like a Final Solution that would eliminate the noise completely--that the noise exists at all is bad engineering. Never had it in any of my previous Camaros nor my Corvette.
