Jeep loves torx so much that the top bolt on the bell housing of a 4.0 is a reverse torx or star or whatever it's called. I was thrilled to have to battle the hardest to get to fastener using a crazy bit. 6point bolts with 6point sockets for this man.
It may be a Chrysler thing vs. just Jeep as I needed the female/reverse star for front drive shaft on a Sebring.
