Here is the write up for my posi lock. This is a litte lengthy. Sorry.
Things you need.

PTO Cable link

1/4 Inch Compression Union link

5/8 Compression Spring link

Gasket Maker link

To open up the vacuum side use a flat head screw driver and work your way around the seam prying it open. Once it is open all the way you can pull the entire thing apart and cut the diaphragm so that it doesnt seal anymore.

This is the one part that i dont really have photos for. Being that my hands were covered with oil and my camera cost more then my jeep did i decided that it was a better idea not to touch it. You need a pair of needle nose pliers here and you need to pull the holding clips from both sides of fork so that the fork can slide out. Once these clips are out you will see the small ring where they hold in place. This is were i only used one of the clips instead of two. While the fork is out drill a 5/16 hole in it so that it will line up with the hole in the case when everything is back in place. When your putting everything back together put the fork back in place and slide the rod back through til you can see the very first clip ring. Put the clip back in place between so that the clip is between the fork and the wall of the case (vacuum side. Also PM me if this doesn't make sense). Now the fork Is held in place but there is a gap between the cable side of the case and the fork. This is where you slide your spring into place so that it is always trying to push the fork out of 4x4. When the cable is pulled it will lock the axel and as soon as you unlock the PTO cable it will slide out of place again.

So there is the basic write-up. Leave me comments if you have any ways to make this better or easier. So far it works quite well(takes a little longer to put in 4x4 but i know its not going to go out)
