How to tell dana 50 or 60 on front?

[PowerstrokeAaron]

Is there a way to tell if i have a dana 50 or 60? Need to order a ring&pinion but the tag is missing and would rather not take everything apart to get the code off the ring gear before I order the parts.

Easiest way is to look at the year the truck was built. Assuming you are actually running a 6.0, your truck is a 03-07 so you have a D60.
