Open the drivers door and look for an information sticker on the end of the door

that shows the axle code

" M " is the 2.73 Traction Lok ( most likely with the automatic )

" Z " is the 3.08 " " ( most likely with the manual transmission )

( also " E " was a 3.27 Traction Lok and " K " was a 3.55 Traction Lok )
