Default How to Identify Traction Control Rear End?

I'm rebuilding a wrecked 99 Firebird and need to replace the left rear axle shaft. The wheel has a slight wobble and there is a loud chirping sound that sounds like the brake disc running unevenly through the caliper and pads.

Most replacement axle shafts I'm finding list them as with or without "traction control". Can someone tell me the best way to determine if the car has this or not? Would it be in the VIN, Manual, rotation of wheels, or somewhere else?

Also, I haven't replaced an axle shaft in a long time (69 Mustang). Is it still pretty much the same on these as in releasing the shaft by removing the c-clips from the rear end? Thanks for the help.

With TCS = 2 speed sensors, one on each axle.
Without TCS = 1 speed sensor on ring gear only.

Or if you trust the door sticker, the RPO code for TCS is NW9.
