with a OD trans 4:10 isn't bad, especially if it's not a daily driver. you have 28 spline axles, lot of people here have slp posi units

4.10s would be fine on a 4th gen 6-speed daily driver with its .50 6th gear, but may rev a bit more than you want on a 3rd gen unless you're really into street racing. Also, the smaller pinion and thicker ring gear with that ratio will not let you slide in the paddle that replaces the spider gear pin if you get a Torsen. SLP has a 2-piece paddle kit for this.
