Well I can tell you it is not from a 80> truck as they had Twin Traction Beam front axles.
You may get more help in the dent side truck area.
What may help is to know the wheel to wheel measurement as the early Bronco's and the same year pickup's used that same front axle but the later Bronco's I think were wider.
I also dont know when disc brakes where either option or standard up front.
Good luck

Post up the width of the WMS of that axle. Looks like full size Bronco or F-150 due to the cast radius arm castings on the axle housing? They were used on 78-79 truck or bronco IIRC? Earlier axle had weld on style radius arm wedges on the 77 and older truck or bronco. Hopefully this information my help you identify what you have?
