Why would you need a selectable locker in the front? The rear doesn't have to be selectable and it goes around turns. If the front is non-disco as a 94 is, when you go around a turn the diff simply acts like the rear and the side bearings allow the shafts to turn at different speeds. If you put a non selectable up front it will definatly chirp and probably scrub when you turn but thats the price you pay for trail performance and a cheaper locker. Just learn how to drive it and it will be fine.
