The stock rear is pretty flexy. Best to upgrade to the ZR2 rear axle. Many of those will have the GovLoc. I like them :)
If you really want a locker and do mostly offroad the lunchbox lockers (Powertrax) do work. They can be harsh and really beat the axles and transmission though.

Should. Some had a different size U-joint and require and adapted cross to fit the driveshaft. Mine was direct bolt in :) If you have 3.73 ratio the odds are in your favor as most were that ratio I believe.

The ZR2 rear will be hard to find and expensive and isn't necessary unless you intend to do some severe off roading, in which case you will also need to reinforce your frame. Do some online research on the different types of units available, they all have pros and cons.

Zr2 axle is a huge upgrade over the original axle in these trucks. No frame reinforcement required, other than the ujoint it’s a straight swap that couldn’t be easier. For a 3.73 truck that has issues with the original rear axle, it’s a no brainer in my opinion. Is that what I did? No, I went with a cab and chassis 14 bolt with 4.10s and a Detroit locker. It’s, uh, slightly bigger....
