Strange '79 axle code
Hey all, I know this gets asked a lot so I'll make it quick: I've searched everywhere but can't find what axle code 11 should be for a '79 F100. Here is a shot of my door plate. Any ideas?

as you can see it is a later code
.
IIRC code #11 is 3.00:1
Under construction.

Hi Mil1on, when you say it is a later code, what do you mean specifically? And why is it not in the standard charts? Is this a Ford axle? Any other info you could give me would be really helpful.
Last question - I didn't see a table for transmissions; could you help me out with the K on my plate? It looks like a C6 but I want to make sure.

Here are some shots of the axle. I tried to get the tag in there as best I could. Could it be a Dana 44? Why wouldn't it be listed in the code charts?

You truck was produced later in the 79 production and the axle ratio code never got put in my version of the Ford parts books.
This code has remained a mystery for some of us as normally a number that low is for a Ford 9"
The axle shown is a Dana axle on an F100 though.
A few of us think it is a Dana 30 or 31
see this Dana ID diagram

Cdan if it a drop out center section from the front, it's a 9", if it has a rear cover it's a Dana, or on 8.8 if from a newer truck. Pictures really help a lot.

Holy cow, old thread alert! You should start a new thread for questions like this, especially since it's a different axle.
