Can't Find Front Axle ID

[Ford460Driver]

I can't find any numbers on my front axle. Where would they be at? The rear has a metal tag. It says:
81
DSO-DOUA
3L50 9 772A

I don't know what that means. If you do please let me know. It has the Dana Spicer 24 Transfer case in it. That tag says:

Serial: T193284
B/M: 300205
Model: 24

What is the B/M #?

I'll try to answer the best I can. DSO DOUA, I think is the bill of materials, its used to order parts thats matched to your specific axle. The number 81 may be included in that too. 3L50 is 3.50:1 limited slip axle, the number 9 i think is name of axle (still trying to find that info), 772A is ford's code for month and year axle was built. I hope I'm right on this but someone else that knows can tell you.
