I have a 72 blazer, 1/2 ton axles, and 33s. I'm a once in a while wheeler, and I don't go very hard core. I'm looking for a locker for my 12 bolt. I'm curious if it is worth going with the detroit in the 12 bolt. Would I be ok with something like a lock right since the 12 bolt isn't that strong anyway? Or is it just worth the money to get a detroit? I'm going to stick with the 1/2 ton gear for a while. I know the best way to go is to get a 14 bolt and drop the detroit in there, but I don't want to go there yet.
