Your are correct I have the rear leaf springs not the coils. Can you tell me what year I am looking for. In my 88SWB the rear end I believe they refer to it as open I want to replace it with the best scenario. I have a 87 SWB with a limited slip diff. and I think that rear end is a better choice. I am not willing at this stage to spend the $$$ for the ARB but I am looking to pull something out of newer Montero if someone can point me in that direction.
