I'm looking into putting air lockers on my 1995 Passport (1st gen.), but I can only find front lockers for that year from ARB. Just wanted to know if any one has done the mod, how dificult it is to do your self, and how much the kit cost. The price wasn't listed on ARB. It seems like the rear locker would be the most usefull. I've had traction problems with the rear wheels when trying to pull heavy vehicles out of sand. Any help would be great.
