With your manual 4.6, you most definetly have the 8.8" rear end. As for lockers, Would you want a full time locker or an air activated locker. For a full time locker, I suggest the No-Slip Traction device from Powertrax. It works like a regular locker but they say that it disengages around turns and such. For an air locker, go with the ARB. This gets pricy though. For the ARB, I paid $780, and will not do the install my self. Drilling into the diff cover is required. For the No-Slip, I think somewhere under 300 would be a good price. They say you can install it yourself in a few hours, it just requires the removal of the spider gears. Hope this helps. Oh, you're lucky because no one makes a locker for the 9.75" rear end!!
