Better check that rear axle tag number again.
WDM-DC is listed for 1980/87 only.
The ratio is 2.47-1. Used on 2WD's
I doubt it was used for a 4WD rear axle ratio, as original.

What is the serial (VIN) number shown on the registration?
Through 1980, Ford VIN's are 11 digits. From 1981, 17 digits.
You can edit your posts, to add further info.
What is the front axle ID tag number?

Sounds like the rear end went out at one time and someone replaced it with a newer rear end that didnt match the front. Either get new gears to match the front or find an axle with the correct gears in it from a junk yard. Is there a tag on the front axle to figure out what gears its got?

We need some front diff info - any tag found there? Hopefully, you still have a decent ratio there (like 3.50, or near) and then you can get rear gears to match. I, personally, wouldn't want a 2.47 geared 4wd.
