I plan on changing the gear ratios in my dana 30 and amc 20 from 2.73s to 4.10s. Will I have to buy new differential cases to go to these new gears or can I do without these? They are pretty expensive, and I don't understand why some companies say that only 2.73 geared axles need to change the differential case. Thanks.

Yes you will need to buy new ones. unless you throw a detroit in the rear.
