How to find what gear ratio in truck?

The build sheet/window sticker says nothing about what gears are in the truck. I can not find anything anywhere in the truck that says what gears it has.
So; does anyone know how to find out the gear ratio in the truck?

Thanks. I kind of figured I would need to do that.
I thought maybe I had overlooked some place on the truck that might say what it is though.

Click on this link & request Dodge for your "build sheet"...they will e-mail it to you. Your build sheet will tell you your gear ratio plus everything else about your truck. Contact Dodge

Thanks everyone. I called dodge today and they looked it up for me. I was told 3.73.
It would be nice to see it on the truck some place though. A person never knows if the person on the phone is just telling you something to get you off the phone or not.

Yotd1976: I have checked every tag on the truck more than twice. First truck I have ever had that I could not find out the information.

Super Briar: I will check it out through that site also to see if it matches up with what I was told on the phone.

If I end up letting it bother me too much I will just pop the damn cover off and figure it out for myself to be sure.LOL

Popping the cover isn't necessary. You can jack up the rear put a chalk mark on the tire and one on the drive shaft and count the number of turns the drive shaft makes for one turn of the tire. If you get 3 and 2/3 a turn then 3:73 pretty spot on. I would still get the info from the web request it gives you a list of everything your truck has. It took 2 weeks for me to get mine back but was very informative.
