Earl,

Is this Moss# 858-385 (#44 on page 118 of the latest catalog0? You're 
describing the problem I have.

          <div>This reminds me of a similar situation that I had many
            years ago on my BJ8 â?? a â??thunkâ?? sound from the left side of
            the dash area (or so I thought) on certain bumps but not
            others. Drove me nuts trying to find it - literally for
            years.  Finally found it when the car was torn down in
            conjunction with the total restoration.</div>
          <div> </div>
          <div>There are 2 plates â?? one on each side of the car â?? called
            wing support brackets in the body manual (plate BC 2) - that
            tie the assembled wing / shroud flange to the top of the
            inner wheel arch.  The manual is not very clear on this
            thing.</div>
          <div> </div>
          <div>When dismantling this part of the body, we found the pair
            of bolt / nut assemblies totally missing and clear evidence
            that this was the source of the â??thunkâ??.  But it sure
            sounded like it was coming from the dash or bonnet.</div>
          <div> </div>
          <div>Your problem just might be that these bolts are there but
            loose, which could conceivably cause a creak type of sound
            that seems to be from the dash area.  Try pressing down on
            the right side fender / shroud close to the centre of the
            wheel cut out and maybe fore and aft a bit to see if you can
            produce a similar sound.  The bad news is that these things
            are a real pain to get to on an assembled car â?? they are
            almost impossible to see, let alone service as they are up
            high and behind the air hoses on both sides, and canâ??t be

                Have been struggling with a new intermittant noise for
                about a month now. <br>
                Seems to eminate in the dash area above left side of
                glove box, <br>
                A creak rather than a clunk. <br>
                So what have I done. <br>
                Tightened everything in that area - starter mounts,
                clecked bell housing, checked brake booster mounts,
                jammed the air vents solid, removed center console and
                still no improvement.Tightened windshield side mounts
                doors checked. <br>
                Was convinced was something to do with the heater
                controls - spent most of one weekend removing and
                replacing it more securely (what a pia job !). <br>
                The noise is not tied to road or engine speed, but worse
                when going over uneven surface, even very slowly. Also
                thought was worse after car was warm so switched heater
                valve off. <br>
                Thought had breakthrough as got a lot better with top up
                that pointed to windshield mounts. But no after a few
                days back as before. Actually sounds like expansion type
                noise. <br>
                It even occasionally does one or 2 creaks when car
                stops. <br>
                In last 2 years had windshield replaced so wonder if
                could be a problem there ? <br>
                Cannot recreate the noise with all manner of pushing and
                pulling of dash or glovebox or airvents and windshield
                in that area. <br>
                Tried jacking the rear end up in case was chassis but no
                change, <br>
