Can anyone decode this for me?

[beast runner]

the axle tag on my 88 eddie bauer bronco reads as follows

S814P

3 55A888D30

 

[Krafty]

S814P Ford F150 Pickup 87-95 3.55 8.8 NL

3.55 gear ratio, 8.8" ring gear,

 

[Elmo]

3L55 would mean it is/was limited slip differential from factory

3 55 would mean it is/was an open or non-locking differential from factory.

As we all know anything can have been changed over the years
