Anywhere on the truck to find what gears I've actually got?

Anyone know an easy way to determine what gears you have? Not sure if I have the 3.21 or 3.92's and not finding an easy way to check..

Plug your VIN into this. It should tell you.
Thank you! Exactly what I needed.. Also just had my wife pull the window sticker outta the filing cabinet thinking it may be on there, which it was, she just sent me a picture.. Appears I have 3.92's..

I had decided if I had the 3.21's I was going with 35's if I had the 3.92's I was going with 37's.. Life just got more expensive!

I think my rear axle or diff had a sticker on it confirming the ratio too.
