9" axle tag decode

WDM-CA is the code on the tag, can anyone tell me what ratio it is? It's in a 78 F150 but I cannot gurantee that it's the original axle so the door tag doesn't do me any good.

Below those numbers are 00 388E

If there's a number before the 00 then it's been rotten off the tag.

Thanks. That does explain why the truck was such a pig off the line even with a 460 in it.

If you trust junkyard axles, 90% or more of the time if you find a F100/150/bronco 4x4 it'll have 3.50 gears most of the time with a limited slip.
