What rear diff do i have

I have a early 99 f-250 SD and i been trying to figure out what i have for a rear diff is it the 10.5 or the 10.25.

the diff tag says i have a 10.5 LS 3.73. But I've been looking around and researching on it and im getting mixed messages on it. Just need help to figure what i need to look for to know what i have

The tag says 10.5 doesn't it? If it were a 10.25 then the tag would have 10.25 on it There are some parts interchangeable between then two. The limit slip might have 10.25 on it.
