How do you remove a frozen thru bolt that goes thru the front spring eye on the rear spring of a Pinto. The bolt is bonded to the bushing inside the rubber spring eye bushing. When you turn the bolt, the steel bushing turns with the bolt, and since this steel bushing is larger than the bolt hole, nothing is removeable. I've tryed everthing short of a cutting torch with no luck.HELP!!! DICK
