Chances are the housing is from 88-89 but that doesn't mean the insides are. Pull the rear cover and see what carrier is inside. Count the teeth to see what gear ratio it is.
You might have a 1989 housing with the 1992 28 spline axles installed into a posi with 3.73 gears.
On the other hand maybe someone broke the original diff and just yanked the first one they found at the auto wrecker and installed it.
