Not for sure what the Q code is, but here's a link to Ford axle codes. You can also pull the pan off and count the teeth on your gears. If it's a 10.25 rearend, it's probably the Sterling full float. It's a pretty good rearend. The only drawback is that they have a weak pinion. It's not really a concern unless you'll be putting 40" tires on and rockcrawling.
