Dana and Spicer are one in the same. There is a 7 Digit number that starts with a 6 stamped on the front of the drivers side axle tube. The last number indicates the ratio the diff was made with. If you give me the first 6 numbers I can tell you anything you need to know about the diffs.

Kandyman is correct. The 603304 only has 1310 inner axle u-joints and the 603396 has 1350 inner axle joint. Both have 30 spline inner axles.

Unfortunately The Spicer books only list from the Wheel Brg's in as far as parts. You could hit up your local parts store with the info listed above and they could tell you if they brake's the same.

Since these are a closed knuckle set up you should have drum brakes.

The brakes are the same if drum brakes. The 396 number is listed as a 3500 lb axle, the other one is a 3000lb axle. Difference is in the knuckles.
