ford 9 " decoding
I have a ford 9 " with the following codes listed on the tag.
woh-t
3L50 8a8 311.
It is hard to tell if this is correct due to corrosion but as best I can tell it is. I need some help is this a 8-9 inch ford . I would appreciate the assistance and what is the proper width for the 54 f-100

If it's a 9" the tag should read 3L50 9
I'd bet you have an 8"
Drum to drum measurement you want is 61 1/4" for stock width. An inch either way won't cause you any problems with reasonable tires.

WDM-T is correct it appears.
It was used in 63-78 F-100's and is listed as a 3.50 limited slip 9" with 28 spline axles. I have a few out back with that same code.
I believe that it is also the correct width for your 54.
Tim, that 8a8 is just a date code. Some tags will have 8 or 9 embossed to the far right of the axle code but it is not a given. Ive seen others marked right after the ratio such as 3.50 8 which is what the 8" under my old 26T coupe had.

Thanks for the info Carl. I stand corrected - 'bout the time I think I've got something figured out, Ford throws me a curve. On all the 9's I happen to have around here the size is marked right after the ratio.
