What differintial do I have?

[mrjordan2u]

I want to Put a cool differential cover on the rear of my truck.
And i want to powderCoat itsince I work at a powdercoating company.
How do I find out what Size or specifications I need to order a replacement?
Should I just go ask the Dodge Dealership in town or is there a way to find out personally?

I have an '03 Ram 2500 4x4 Heavy Duty SLT
Hemi 5.7 short bed quad cab.
I know it has 14 bolts. What elsse do I need to know?

Any Ideas?

there should be 2 metal tags held on by two of the diff cover bolts that tell you which rear end and gear ratio. hope this helps

Also, since they are mostlikely dana's, if the tags are not present, but they should be, dana stamps the housing with the diff number.
