D60 front axles
The 1989 Ford Dana 60 I just ordered in looks like it has an adapter to me. I havent pulled it apart yet but it looks like the hub comes off and the adapter unbolts from the rotor then I bet you could just reuse the same bolts as your studs. Worst case is I will have to remove the studs from the adapter and press them into the hub again.
If it wasnt dark I would take a picture for you.
Later,
