Outer Limits 4x4 Board

Just about to buy lockers that are already set up the lad wants to do a diff swap so I dont have the numbers to reference the diff ratios.
So who knows what ratios does a 4 door 4runner/surf (I think it a 92 model or there abouts) run as stock ratios the owner does'nt know.
I have 4.8s and would like to keep this ratios

mines a 90 model and it has 4.8's

cheers

22r 4.8`s ,V6 4.3`s

Thanks its a 4cyl thats a strait swap.
Means I get lockers sooner
