i purchased a 1992 montero sr a few months backm its in awesome shape and i want to learn moe but its been hard finding the right answers

many people say that if the sr came with headight washers, bouncy seat, then most likely it has an lsd or selectable locker.

i have the above featues except the lsd and a locker
what are the differences between my sr and aa fully loaded sr/ls of the same year?
