I swapped out my 3.9 V6 for a built 5.9 V8 ( well, its really bigger since its bored 40 over) and I'm ready for a heavier duty, LSD rear end. I want one from the same year as mine, don't I? but then, the '97 didnt come with a 9.25. will a '98 or '99 work? with minimal modifications for fitment? I'm not sure how much power the 9.25 will handle but that's the heaviest duty axle that fits under our trucks, right? Thanks for any information.
