Hi i am in australia and have a 1985 bj70 with leave springs all around. i want to buy a 2 inch lift kit for it but the problem is not many people have a listing of the vehicle as its quite rare in australia. so after abit of research people say that you use bj60 rear leaves and hzj75 front leaves does this sound correct? also theres are pre and post 1985 bj60 rear leave. which one do i use? whats the difference? if this is correct do i use all 70 series shock absorbers front and rear or 70 series front and 60 series rear shocks? also do the shackles swap over from the 60 series to the 70 series? so either one should work? Thanks sorry for all the questions but even the suspension experts are unsure of what fits my vehicle.
