Asking what is in your rear end is not always a safe question around here...:roflsquared:

You would need to set up those gears, if you've never done it before I dont advise it. The cheaper route would be a slip in spool like a Yukon or a slip in locker like a Lockright, like the ones here...

You'll have to pull an axleshaft and find out for sure if you have a 28 or 30 spline before ordering just to be safe.

ive been looking thru summit and a spool, c-clip eliminatiors and gears rounds up to like 400 bucks with out the bearing kit, is it that hard to put a locker in?

A full spool, full locker, or anything you're going to have to bolt the ring gear to is going to have to be set up again. You can do it if you own or have access to the tools to do it. Dial indicator and base, caliper micrometer, ft/lb and in/lb torque wrenches, bearing press, 450 ft/lb impact...

I did a write-up when I did the r&p in my 14-bolt, you can see it here...

...but the setup for your 10-bolt will be a little different. So THIS is why I recommend a slip-in locker or spool, so you dont have to monkey around with setting up the gears all over again on a full spool or full carrier locker.
