Hey guys! New to the site, and I have a couple questions. First, I have a 96 Dakota, 5.2, auto, 8.25 w/3.55 gears, regular cab, short bed, 2wd. I REALLY wanna try a TrueTrac locker, but I don't know which axles I have. I read online that SOMETIME in 96, they switched from 27-spline to 29-spline axles...TrueTrac is only available for 29-spline. Short of pulling the diff cover and counting splines, is there any other way to tell which I have? Second question...should I just find a 9.25 and put it in instead? Pros/cons?
