Help Decode Diff Tags
I bought a 1990 Bronco XLT (302 AOD) but am not sure about the differentials.
Rear has 2 lines of numbers:
Top line: S844A
Bottom line: 3 53 88 9H30
Front has 2 lines
Top: 3 54 (upside down triangle) EDE8TA SC
bottom: (upside down triangle) 61010-2
I assume the rear is a 3.55 open and the front is a
Dana 44 open 3.54 which is what the door plate says but these could have been changed/modified.
The tag on the Borg-Warner Transfer case
Top Line: H269 3 1356-38
Bottom Line: 107251 E9TA-MB
Thanks in advance, rlh

The rear diff is a 8.8 inch open diff with 3.55 gears. The front is a Dana 44, 3.54 gears. I don't know about the t-case, other than its a Borg Warner 1356. Hope this helps!
