That's a neat one too!

The only thing that one does NOT show is RPO codes..

I'm unable to discern axle type or diff type when looking through the specifications.
RPO codes will show if the 9.5" AXN axle and G80 was installed.
Are you looking at a vehicle online, and can't peek at the RPO plate on the glovebox door?

Kind of.. I purchased an axle, but the recycler only had the VIN number.

Sellers usually have a photo of the VIN, but not the RPO codes.

Hope that helps. I contacted one of the GM representatives that used to frequent this forum and had them send me the build sheet for my Burb many moons ago.

the only way to get build sheets for free anymore is from a dealer, service counter or parts department counter. the chat reps are no longer allowed to give them out
anywhere else is generally going to charge for them

Insert VIN after the equals sign.

Insert VIN after the equals sign.

When you run this, the RPO codes are shown as the first 3 digits of each description in the second column. Reference 1SM, NZZ, ZM9, 522, 52I, 6XK, etc.
