I posted this once before and will try again. I need a new rear speaker tray or shelf for my 73 2dr dodge polara.I see a company that will cut one for a 72. I thought the 72 and 73 had the same body style and rooflines the only difference were the front and rear designs. I thought the interior dimensions and style were pretty much the same and I am thinking this 72 speaker tray will work on the 73.I have had no luck in getting part numbers to match. Any thoughts and suggestions would be appreciated and by the way Merry Christmas to all on this website!
