Another Rear-Diff, Axle and Posi Question...
 

I know there are plenty of threads talking about the different carriers to use and which will go into what, but I haven't found one that answers my questions specifically.

So I have came to a place where I need to replace both axles due to being bent and I have bad wheel wobble, so I figured while I'm doing that I may as well make it posi.

I have an LS motor with the 4l60E tranny going to a 12bolt. What do I need to make my truck have posi(ie. carrier, bearings...), and what do I need to replace while i'm replacing the units(anything that will be needed to make it fit or stronger). And lastly if i'm getting a 30 spline LSD then I just need 30 spline axles correct? What about lengths?

Assuming a 12 bolt rear diff and a small block I would lean towards a True-Trac
