Some additional info I have found on the speaker grills. The originals are thinner on one side verses the other, If you look from the top before installing you can see it. The thinner side goes towards the rear. the aftermarket set I bought from a upstate New York Camaro Firebird supplier looks just like the better one in the right of this post and is also built thinner on one side like the originals. Also from what I can gather from assembly manual info I have read the grills were painted the color of the kick panels.
