It comes with everything you need minus some RTV sealant. The only thing that some people might require is the plastic cup that fits on the end of the shifter ball. I have a 27 year old Mustang and it didn't need it, so you should be good.
Just lay a THIN Bead of RTV around the shifter-to-transmission opening, let it dry for a about 5 minutes then smoosh the shifter down on top of the RTV. Be sure not to over tighten those bolts. It doesn't need to be superman torqued down. Just tight enough to keep it from going anywhere.
