72 duster resto

What's the alternative? Take the whole thing apart so you can get the hub in a vise?

Is there going to be sufficient clearance behind the hub to get the new longer stud in straight to thread without having to take the hub off?
Yeah, there's not many alternatives it seems. The hub with the stud positioned at the bottom of the knuckle is just barely at an angle to get it in, but wouldn't know til one of the studs is fully out to test fitment.
