well when I first got Mera X, I was trying to see inner workings to clarify if X is indeed a Mera and if i remember correctly....there was a bondo looking substance holding mine. may there are bolts/nuts under that to keep them from working off. let me see if I can reproduce the image in photo.......
*EDIT*
so maybe not with the bondo. if you take the screw out of the rubber molding you can see the top of the bracket kinda.
but no I never have.....hope someone chimes in that has and took pics as well

this may be interesting and another way to help quantify a Mera...in the end also. good question
