Is an 87.
Diff lock has a high and low drawing on it (up and down)
And push to the left to engage it but if you push left you can't go up and down?
Don't see a low range option anywhere? Unless you mean just shift it into 1st? Did try that but it didn't do anything.
Sorry about my confusion......this is my first auto car as always bought manuals before!
