The letters S-O-L apply here. The ABS uses a speed sensor for the rear wheels that mounts in the differential and counts the teeth on a tone wheel mounted to the gear carrier. It's going to take a lot of work to duplicate that setup in an older Dana 60 case.

Getting a newer D60 with the required parts would mean discarding everything except the axle shafts, brakes and gearset. I guess you could swap center sections but that would be major. Use the D60 in a vehicle that doesn't have
ABS, or else mounts the speed sensors in the brake housing.
