What is the model of Tito Jackson's guitar (of the J5's)?

I think it might be a gibson es 335 but probably not because of the pearl on the fretboard...can you please tell me the model, year and the name of the long metal part that attaches to the bridge? I have a picture of his guitar on this link: https://picasaweb.google.com/golferthatwins/Pictures?authkey=Gv1sRgCK3_7ruYx77I4gE#5624094079648088562
