Help Identifing an axle
Hi there,
I'm usually hanging around the 48-60 Ford Trucks section of the forums. I have a question about my axle that maybe someone can point me in the right direction for identifying it. I pulled off my bed this afternoon which made it much easier to read the tag on the axle, although it did not say FORD on it anywhere. I know its a FORD since the bolt pattern is.
Anyways the tag reads
EV AA1 7CB
75 9 718A
I looked up a TON of sites for ID'ing tags but everyone starts with a W.. If I read it wrong or it was just that dirty it might have been WAA1 but i doubt it. Any ideas?

Your number is a pre 1963 number but unfortunately all of the Tag Info starts after that date.
I think Ford started using the W in 1963. Before that if you did find a reference to your tag it would be just for the housing.
Before 1963 you need to take off the cover or remove the carrier and get the numbers off the parts. Of course if you have it apart you can count the teeth and get the Ratio.
This is just what I have found but I could be wrong.

Awesome, thanks for the info! Someone on the 48-60 sites posted the same thing. Is there a site you guys found this from, or just know this like the back of your hand. =)
I know this might be a newb question.. but what is the benefit of that ratio vs. a 3.0 or a 4.11? I was told that the 2.75 was a good gear ratio for my 460/C6 tranny. My other truck (a diff. 1955 F100) had a 400/c6 with a 9" 4.11 posi? Or at least thats what I was told.
thanks again!

i have learned most of what i know from hangin around this site.
2.75 is going to give you better gas milage and more top end speed, and slow off the line. you probably wont noice too much difference between that and 3. 4.11 will shoot you off the line but you will wind out pretty quick and not have too much top end speed.
