Here's a pic of the bezel that was in my '68 SS/RS, deluxe interior, when I bought it in '83. It doesn't match the dash panel . The color is off just a bit (not sure if it's burlwood, Dan) and the grain goes in the opposite direction. The part number on the back is 3886998. I've since replaced it with a repop black one.
Ed, do you think the one I have pictured is a Firebird bezel?
