What do I have? '87 22R, 5 speed. Do I have a chain or gear driven transfer case? Bigger tires will happen soon and if I have a gear driven i'll maybe want to swap in Marlin's 4.7 gears. My shifter is like this:

------4L
2H----N
4H----4H

Thanks guys.


'87 4Runner. '83 Honda XL250R. No mods on either.
