Legend
35 might be 3.55 gears but best way to tell is to either pull the over and change the fluid or hooking up a tach. if you got 3.21 gears the engine will run at about 2000rpm at 50mph or 2000rpm at 45mph with an automatic slush box. if the truck is a standard it most likely has 3.21 gears. stardard trucks are always geared like that.

-you could remove the pan cover and count the crown and pinion teeth
-you could raise the rear end, spin the tires 1 revolution and count the turns of the driveshaft
-dealer build sheet; call the parts dept and provide your vin. Call fca corporate and they can email you a build sheet.
-try the vin decoder in the tools section
