Rear end Codes

Need help identifing my rear end codes. I checked a few
charts that I found but nothing seems to match the codes I have.
Here are the codes as seen on rear end tag:

S 909 A - 1
L55 9 75 7A02

my truck is a 97 f-150 5.4L SuperCab Stepside with the
tow package.

Thanks for any help.
John

Rear end Codes

Look in the driver's door frame for the Ford MFG sticker.
Last last row of data after the bar code will have the word 'AXLE'
under this word is a two position code:

19 - 3.55 NonLimitedSlip
18 - 3.08 NonLimitedSlip
H9 - 3.55 LimitedSlip
B6 - 3.73 LimitedSlip
