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....
Why couldn't you mount a tone ring on the pinion grease slinger with the right number of teeth? Pickup mounted to the snubber?
I think that is what his 9.25" has on the front side of the diff, but I have not been under it or opened the rear cover...I will ask him. I plan to build a few more Dana 60s because I have the case spreader, the setup bearings and a large pile of shims. And once you build one they seem to last forever regardless of how you beat on them.
