My 73 came with 3:08's in it new & all i had to do was change the gears to the 3:73's that are in there now. As long as it's a 3 series carrier you can bolt up to the 3:90's in it with no other parts . When you go to the 4 series gears then you will need a different carrier or a ring gear spacer. That has been my experience so far with changing gears.

But that is for an 8.5" rear end where the 3 series carrier works with 2.73 3.08 3.23 3.42 and 3.73 OEM gear sets as well as the aftermarket 3.90 and 4.10 ratios. Not the case on the 8.2" carrier discussed by the original poster.
