If you are talking about the top line on the tag of an 8.8 it tells what trucks this rear end was used in and the plant that made it.
You can look up the code in a Hollanders Identification Manual.

I think what you are looking for is an "H9" from 1992-1995 F150 (maybe also 1996 but can not remember the year they changed the spread, it was 96 or 97).
This should be a 3800 3.55:1 LS.

Your "18" is a 3800 3.08:1 open.
