(thom-b) is correct,, "PATIENTS" even with this it's a hassle. I've done it all, and it broke. Ended up Arc welding another bolt head on to the existing remainder hanging out and repeating over night soaking of rusted bolt remover solvent. Engineers design these bolts to do just that, rust up and brake, then repair at dealership hahaha yep not like the good ole day's back in the 60's 70's while racing at the grudge races on FRIDAY & SATURDAY nights EH!! Good Luck with this if you have an arc welder, or spending $100.00-200.00 at H Freight tools (shop around) be sure to get the gloves and arm protectors and Face shield.
