We need to find what 'WES-T' means. 3EB is the date code (year,month,week), 2.75 is your ratio, 9 is a nine inch (good!) and 951C is the plant code.

************************

Got it. WES-T1 is a conventional removable carrier axle, I think that
makes it easier to change gears. Also is a 2-pinion setup whatever
that means. Info came from my Ford shop manual volume one pages

15-10-03/15-10-20. Okay now i feel a little dumb Haha [Image: ford9traclockblowup_large.jpg] In the center of this photo is a square block with 4 small gears around it. Those are the pinion gears 2 pinion diffs have the two gears on the long shaft only. The 4 pinion unit adds the 2 extra gears on the short shafts.

I have decided to go with 3.25's be a little better than 2.75's plus with a lot of highway use and cruising i think anything more would hurt me

I think you will be happy with 3.25s.I took the 2.75s out and replaced with a (N) case 3.50s in my Mach1.Freeway driving did suffer a little.

the 2 pin should be a open carrier (not posi) the 4 pin would be posi.

Thats what i was thinking as well until i saw that in the chart NL2 - non locking 2 pinion, NL4 - non locking 4 pinion, L - locker from what i gathered the 4 pinion is a heavy duty rear end
