You will have to decide on what differential you want to use, 2 Series or 3 Series. If you retain the 2 Series Differential, you will need the thick gears. If you go with the 3 Series, you use the standard gear set. You can find the 3 Series Differential for sale in the For Sale Section. If you go with the 2 Series Differential, Strange has the thick gears that will work. Another option is to buy the 10 Bolt Rearend from a M6 that already has the 3.42's and just install the entire rearend. This is the route I took and it was easy work.

Unless you just want to buy a new series 3 carrier (usually about $300-400) you are just looking for a GM 7.5" Ring and Pinon gear for a series 2 carrier.
For a 3.42:
Motive Gear part # G875342X
Richmond Gear part # 49-0005-1
USGear (Strange Gear) Part # 01-875342X
SummitRacing.com lists them as part # RMG-4900051
jegs.com lists them as part # 836-49-0005-1
also @ jegs.com part # 555-60008
While you are in there you might as well get the Inner Pionon Race & Bearing, Outer Pinon Race & Bearing, and a pair of Axle Races and Bearings.
When doing all of this you will also need two axle seals, a pinon seal, some gear oil, crush sleve, pinon nut, shims, differential gasket, etc. Get the "delux install kit" usually ~ $200 from anyone, like http://www.thunderracing.com/catalog...id=256&pcid=67
Jus tlooked and Thunder also sells the gears you need for a series 2 carrier if you go that route http://www.thunderracing.com/catalog...id=287&pcid=67
It's typically much cheaper to just buy a rear end from a M6 and swap it with yours.
