How often do you wheel it that you really need it locked. Considering it's your daily driver, a welded rear is a PITA. But if you wheel it a lot and need a locker, it's definitely worth it. I have a 29 spline 8.25 welded on 33's. I just re-welded it because after about 6 months, the welds broke (I think it was prob. due to using a 110V welder and being less generous with the amount of welding). This time I welded the crap out of it with a 220V welder and welded the spiders to the carrier. It should hold this time!
