Ken Fichtner, Fred Beans, GM Parts direct, and others would be a good start. You can get a 3.42 differential from lots of places, but these guys and others have the Getrag 3.42 diffs and for reasonable prices.
If you will be doing any drag racing then it is a good idea to upgrade the stock torque converter with a higher stall converter as well.
Be advised that PCM tuning for proper scaling from 2.73 to 3.42 gears will be required.

All good companies. I bought mine from http://www.tbyrnemotorsports.com/index.html Make sure you get the ZO6 rear, it is a little stronger due to shot peening.
