What is meant by the term a "lunchbox locker"? I know what a locker diff is,a limited slip diff. and a open diff. But I heard this slang used before to describe a locker placed in the rear Dana 35 axle but could not get a straight answer on what one is.
Thanks!

It's a locker that is basically "open" when there is no drivetrain power going to the axle and it is locked when there is torque applied. They're less expensive than a full locker or selectable locker and less harsh on your drivetrain than a spool or "lincoln locking".

Your options are the Yukon Spartan, Aussie Locker or Powertrax Lockrite. I'm partial to the Spartan myself.
