Rear end information

[glessen]

Hello,we got a different rear end for our Galaxie. I do know it came from a Lincoln Mark Series. However I am trying to break down the rear end code to see what gear it is.

Tag states:
WGB - AB 7AA
50 9 461A

Any help would be great

Here's the Ford codes:

And here's the Dana codes:

Can you ID it as either a Ford 9" or a Dana product, then use the above charts?

9" 2.50, 28 spline from a '77 Mark?

Those are some serious highway gears
