i had a bolt specialist come out and do mine as both of my left hand bolts were sheared off,it took him hours to get the rear bolt out and he had done this on fords before,he had to drill out the bolt and broke several easy outs in the process and had to collapse the bolt with a special tool ,i have now got hair line cracks in my block haeded towards the welsh plugs arrrgh :
It cost me about $120 to get these bolts out but if he had troubles i would have had definate troubles if attempted by myself
