Need help figuring out which Rear Driveshaft to order?

[Texasdeere]

I'm at a disadvantage here as I have no RPO Code Sticker on my truck as it was a theft recovery.  I keep seeing these "aa codes" too?  Like "aax2 and aa4m" when trying to figure out which one I need.

 

Anyway the truck is a 2014 GMC Sierra 1500 SLT 2WD Crew Cab Short Bed with a 5.3 pretty ordinary stuff here.  I pretty sure 3.42 Gears but again no Codes

 

I'm wanting to buy a steel driveshaft from GM.  They are bout half the price of aluminum.  There is just so many!

 

I think it may be 23242264

 

Let me know what you think?

With the VIN you can get it all. Call a dealer.
