How do i find out what kind of diff i have? is there an easy check i can do to see? i think i have a g80 but not sure. car manuel says that i have a limited slip diff? not sure of the difference between that and the g80... any help would be appreciated thanx

 

Run your VIN through here, it'll tell you what you're looking for, plus a lot more. link

 

thanx for the info and the link. found out i have an open diff. now how do i get a posi- rear end? looked into some lunch box lockers but they lock all the time under power so u cant turn under power which may cause problems since my rig is also a daily driver. just looking to see what my best option is and the cheeper the better. plus i do most of my own work with my father so the easier the better. lol any help would be greatly appreciated.
