You will need a three series carrier designed for 3.08 or more. You can however get a thicker gear designed to replace the 2.73 so that a different carrier isn't required. i would opt of the carrier, personally. As far as pinion shims, those are included in a kit and many different thicknesses. The gears must be set up with gauges and each one takes a little different configuration. There is no "out of the box" answer. I've even had shims shaved in order to get just the right clearance.
