I got the number that was on my rear end the number is

WES T1 85A
2 75 9 951A

This was stamped on a SS tage on the rear end will that possible tell you what the gear ration is or how could i figuer that out.

 

WES T1 = Axle model

85A - Year, month, week. Built the first week of May in 1968

275 - 275.1 Gear ratio. Man, what a highway rear that would be, but around town?

9 - Ring gear diameter

951A - Plant coding.

 

That is a 2.75:1 ratio 9 inch conventional rear axle used on a 1970 and 72 vehicle. The 9 951A are supposed to give you the year, month and week but your spacing makes it difficult to make out.

i put the same spacing that is on the tag i guess i could take a pic

 

Say what?? Where are you pulling this 1970 and 72 out your magic hat? 85A is the stamping for a 1968 May and first week of the month production number.

 

Golly gee uncle Glen, after two Mai-tais, I can still read: Ford Car Parts, Section 40, Page 5, type WES-T1 used on 70 and 72, a WES-T2 used on 71. I don't make the rules.

But is is 5th gear-

 

 

was hard to get a good pic

 

Typical Ford, document one way and do another. The format is supposed to be:
-First line WES-T1 (revision)
-Second line 2.75 (date code - formated as '9A3' year, month, week) (plant code '123')
Not unusual.
