The ring gear diameters are as follows:
14 semi float 9.5 inches
14 Full Float 10.5 inches
Eaton Full Float 12.25 inches

Actually, the Eaton he is probably referring to has a 10.5" ring gear. The 12.25" ring gear axle was an option in one ton trucks, and is called the H110. The diff cover of this axle was welded on instead of bolted on.

But I agree, I would keep the Eaton too. Actually, I am going to swap out my 30 spline dana 60 for one with a detroit locker.
