I have not measured it yet but my feeling is it is a 4.10 or so. Would like to get a 3.0 posi but need to know how many splines stock axles have.
Any info or pointers would be welcome. Thanks
Your truck should have 31 spline axels. Most 31 spline axels have a round counter-sunk center, as opposed to a larger Oval in the center between the lugs...
