So it's not really that hard to get them out. 6 Bobby Long 5/16 pins, ARP Hub Studs.
I welded a nut on them and pulled em right out.
If the pin broke flush with the hub, place a nut over the pin and weld it to the pin, take extra car not to weld to the hub, allow to cool, spin the nut a few times and pull it out with a slide hammer
If it broke inside the hub, take an oxy acetylene tourch and get the pin red hot. Allow it to cool slowly. this will take the hardness out of the metal. You coudl then drill, tap and pull it out. You will prolly have to drill and tap all the holes again but should be good to go!
