sorry one last question. I want to know what the kit would be called? a rebuild kit, service kit?? I mean I don't want to order the wrong thing and yukons website isn't working for me and Toms differentials also doesn't show up. so I am kind of stuck. if someone is free can they maybe post a link to find these kits for converting the stock rear to a posi.

It's an installation kit. It will have pinion and differential bearings, pinion and differential shims, pinion seal and nut, crush spacer, ring gear bolts, gasket, gear marking compound and thread locker. If you are replacing the axle bearings and seals you will need to get them too. They don't come in the installation kit. Call Randy's or Tom's and they will get you exactly what you need. Get their best kit, not the cheaper one.
