Ring Gear Size?

[SParman]

I'm trying to determine what size ring gear (11. 5" or 10. 5") I have on my

'05, 4x4 2500 to find out which Diff cover to order.



The PML site says it's printed on the door label or glove box label, but I don't see it.



The Mag Hitech site says most Heavy Duty 2005's are 11. 5". Can anyone help steer me in the right direction please?
