Re: posi help
Check out an Auburn or Eaton limited slip, they are a much better / stronger unit than the factory Gov-Loc style.

Re: posi help
Yes 4wd is the same, but has 6 lug axles. The 8.5 is a 10 bolt. Older trucks will have 12 bolt rear axles either 5 lug or 6 lug. You need to make sure you are getting the correct match to what you have.
