Look for one then slap it in then do the upgrade kit at the same time way better then a ture track "torsion diff" cltch is far better for a truck
2 pinon vs 4 in the cluthc pack diff's the torsion mk3 diff will die at about 400 there very weak mk2 will take about 400 to 500 foot pounds of torq on slicks and it will be ticking time bomb mk3 will take about 800 to 900 not many people brake them
Hey Tony how much were you askin? And what ratio? My truck blows motor mounts and driveshafts like crazy, hopefully a deeper gear will help
