Re: 12 Bolt 3.73 Posi Bundle... Worth a fart?

I'm getting a little confused while shopping for these GM 12 8.875" components. I need your help...

I currently have a 3.08 ratio which means I have a 3 series carrier... Is this correct?

When shopping for rear components, I keep finding posi units for 3.73 and up carriers. Does that mean I will have to purchase a new carrier for my rear to make this work? Forgive me if this is a stupid question.
