Ford 9" Question

[ONE37TUDOR]

Does anyone know what all the numbers mean on the TAG on a 9" ?
Or, could tell me where to find the information?

I have a third member ont of a 61 Galaxie and the tag reads;
WDD - L
3.00  5GC    1

I have another out of a 63 Galaxie and the tag on it reads;
WBS - AG
3.00  2LA    101

I know the 3.00 is the raito but I am curious if the other numbers and letters mean anything?

Thanks,

Scott...
