8.8 swap

$228.99 for a carrier with the carbon fiber clutch pack installed seems like a really good deal. The clutch pack alone is $107.96 and I could probably sell my old carrier to make back some of the cost. Assuming I'm keep my old ring and pinion (I'm happy with 3.73), this seems like a bolt-in traction-lok rebuild. Would this be as simple as leaving the pinion alone, putting the old ring on the new carrier, installing it and putting in new fluid? Anything I'm not considering?
