I am trying to install the large rear plastic trim pieces in the hatch area on my 1976 280z.  I am having trouble getting the pieces around the ears that that hatch struts bolt to.  Both sides.  Are the ears supposed to unbolt?  Mine are tack welded in place.  

Are you sure there isn't a nut behind it??? 

The piece should be removable.  There should be either a 10mm or 12mm nut holding the bracket

in place.

There is a nut on the back side, you'll crack them if you try to remove them without take off the bracket.

Thanks guys, I don't know why I didn't think of a nut on the back.
