dustin,
 the rod pin is tapered on the ends.
 its a one piece pin.
the inner races of the main bearings are shimed to the width of your crank now and where the bearings are seated in the cases.
 if you replace the rod and pin you will need to re-shim the inner races of your main bearings to allow for any differences.
