Are you refuring to the black crossmember that bolts to the tailend of the tranny and then to the body? Or the mounting brakcet on the tailend of the tranny itself? Both of brackets that bolt to the tranny and body are the same (bitemark46 can tell you this aswell). As for the bracket on the tranny itself in not sure if there the same or not.
I just know the new tranny is longer then the one I took out.
