The little b****ds out sorry the stud I mean, cut it off flush and drilled it out and re tapped the thread even after 4 days soaking in plus gas, heat to red hot three different sets of stud remover it was solid. so bit the bullet and drilled it out still didn't want to give up had to use a tap to clear the threads it's been a pig after an hour it was done and new stud in. Several pints of the amber nectar  are now being consumed
