Part number for Sound Bar

I was looking for the sound bar that are in some later model cherokees before they changed the body style. i have a 90 XJ and would like to put this sound bar in my jeep. it is that fiber glass bar that goes in the back that is supported by the trim on the ceiling can anyone help or does anyone want to sell theres color is not an issue bc i will just have it painted. can anyone help?? if no one has one is there any part numbers they can give me so i could buy it new?

Try ebay and the local pick a part yards, I got mine from a yard after a few months of looking. IIRC the sound bar isn't available new anymore as it was included in DC's XJ parts blowout a couple of years ago.
