I will check it and see if tying it down helps, but I have my doubts.
After sealing off the rear bulkhead behind the seats, putting dynamat on that bulkhead and the floor and the sides adjacent the seats I noticed the sound appeared to be louder. Probably more noticeable since the coliepie of noises that come from the rear has been dampened.
Since the noise happens with the clutch actuation and the noise is louder with the camera on the dash as opposed to being located on the roll bar I am inclined to think it is in front of me and not behind me.
Thanks for the thoughts Bruce.
