welding the LS unit is not going to be as easy if you were welding an open rear. Welding an open rear is fairly simple but a LS is more difficult. But I am with these guys^^ don't weld it anyway get a GOOD LS unit or get a selectable or automatic locker. I have an automatic locker and I love it.
The locker works great and I never know its back there unless I really need it. Then I notice the difference over the LS I had. On the road I never have any problems. Driving it in the rain was not much different than my LS so I guess the LS worked well.
