I have a 68 Cutlass Convertible it does not have posi , I suppose it does not have a posi unit. I am sure it has a twelve bolt do you have a posi unit I can install without replacing the whole rearend

You need to know what gear ratio you have to determine what posi unit you need . Some of the Cutlasses had Chevy 12 bolts in them , you need to find out if it is the o-axle or Chevy style . BOB
