yo CAMO

here is a good guide to ID it

Excerpts;

All Spicer IFS (independent front suspension) type axles are identified by independent stamped steel support arm assemblies. The left hand (drivers side) support arm also serves as the carrier cover.

Bill of Material and gear ratio are stamped on a metal tag secured to carrier cover. Bill of material is also stamped on housing between oil fill plug and wheel end.

The Dana 28 IFS is pretty easy to pick out of a crowd, since the front cover is actually a component of the suspension. When Ford began production on the Rangers and Bronco II’s, the company used the Twin Traction Beam-style front suspension that was popularized on the F-series trucks. Essentially, the Dana 28 is a downsized version of the Dana 44 IFS used in 1980 – 1997 F-150’s, though it’s a bit smaller and has a 12-bolt cover as opposed to the D44’s 10-bolt cover.

D28 Ring Gear Diameter: 6.625”

D28 Pinion Gear Diameter/Splines: 1.312” /23 splines

D28 Available Gearsets: 3.08, 3.45, 3.73, 4.10, 4.56, 5.13

D28 Available Lockers: Dana Trac-Lok
