Were those from a 250 or a 350?
Is there a tag on them, or could you see the door tag? On the 250’s and Excursions they used a monobeam D-50 (what I have). It is still a strong axle. My son had his 96 F-350 with a D-60 sitting next to my Excursion, and comparing them, they are similar in size and build.
I know Ford did use a D-60 also… so that is why I was wondering. Either way, you got a good deal on that axle. Just make sure which one you have, because at least some of the parts are different between the two….
