All the RFS cam bearings are the same, i.e. updated after '01 to sealed bearings. The newer cam sprocket will bolt right up.

The old cam gear used a bolt and nylock nut as a stop for the auto decom mechanisim. the newer ones have no bolt/nut the stop is part of the gear. There have been many motors that the bolt has come loose. If it does the damage can cost $1000 or more. The securing guide has a screen on it that covers the oil passage into the crank just incase anything goes south in the topend it keeps it from getting into the crank area (most of the time anyway)

I would check for the updates just to be sure and update anything needed. At most it will cost you $100 and some time if you do it yourself or $250 or so if you have a shop do it.

You'll need updated
