Hi Paul
Both of the carrier's will need to be changed. The front is a 3.73 and up Split and the Dana 35 rear split is at 3.55 and up. Now is the time to consider locker up grades. I would recommend the Detroit True Trac for the front http://jo.my/7ztor4 and a Detroit locker with axle upgrade for the rear. http://jo.my/7n1q6p If you are looking to simply replace the carriers with oem units the front will be the D/S706008X http://jo.my/fkmct2 And the rear will be either the D/S44590 http://jo.my/xnxd0u for the standard open differential or the D/S707243X http://jo.my/alsqzh A inexpensive upgrade and alternative to having to attempt to rebuild the limited Slip is a new unit D/S74210X http://jo.my/y8ckua Thank You
