Everything should swap right over. I did the swap last fall from a 3 bolt to a 4 bolt- dont even know the year-...
If you dont have enough bolts just go buy some at the hardware store. If you want stronger ones, get the heat treated style.
It was a PITA but just took patience and correctly lining up parts. One thing I remember that was a bitch was connecting the bolts that go in through the top. Theres not much room up there for a torque wrench and your arm. Have fun
