Yes, there are a lot of gears that will fit that rear end. It's the corporate 8.5 that was used in many GM cars and trucks from '71 and up. There are gear ratios from 2.41 to 5.13 for the 8.5. You can also upgrade it from 28 spline to 30 spline axles with a 30 spline Eaton Posi and after market axles.
