The stud on the left (along with the other three) was pressed out of a 
spare NOS hub I had here on the shelf as a spare.

The stud on the right is the damaged one I removed from Thirteen's rear
hub that was holding the wire wheel adapter on.  I one of the studs
removed from the hub to replace the damaged one pictured.

Now supposedly the wire wheel studs are suppose to be shorter than 
stock metal disk wheel studs.
