Front axle nut size for a 600ss 
  Could someone please tell me  the size of the front axle nut on a 96 600ss?  I need to get the front wheel off for the first time and have found that instead of it being a standard nut it is instead hollow and requires an allen key style socket that is much larger than i currently have  
 
 Also any idea who sells such an item, preferably tht will fit on a 1/2" drive?
