depends on what mods u have done to truck to pick gear. and try jegs or summit on the gear and limited slip it self. u have a 7.5 10 bolt rear end in your truck now. look for a gear that will fit it. 7 5/8 ten bolt is what a camaro have and the 7 5/8 gear will not fit the 7.5 housing
i looked on jegs and it has a 7 1/2 88- up, but it only says 3.23-up. it also says 28- spline. im sorry i dont know anything when it comes to gear ratio.:uhoh:. plus it put the 7 5/8 in the same category, it doesnt give you a choice.
