was wondering about general diferences, durability, effectiveness? basically looking to lock up my front and was wondering about detroit locker vs. ture trac vs. ez-locker besides price that is! most bang for the buck... ez-locker looks simple to install? the locker looks like it would replace the whole carrier assembly too, so it cant be that hard to install right? I know there's gotta be atleast a few of you who have an opinion on this!
