You'll either need to step up to a 3-series carrier, or buy gears designed for a 2-series carrier.

This is what I found for the jegs brand ones on their website, should be what you want.

p/n: 555-60008

GM 7.5" Ring & Pinion
3.42 Ratio
41-12 Teeth
For 3.08 Ratio and Numerically-Lower Carriers

7.5" and 7.625" gears are the same.

What skanitz1 listed will work. Why don't you step up to 3.73s?

If your car will see strip time go with 3.73s..Richmond gears seem to have some whine, at least mine do.
