The big Front Carrier is the same between gen 1 3.0 and GenII 3.5. However the gears are cut different. The smaller Carriers on the later 4 Cyl and the Gen II 3.0 are the same once again with different gear cut. The Gen 2's (both small and large) are high pinion. Not sure how or if the entire assembly will easily swap. No one has documented it yet.
