I just finished trying to replace the alternator in my 91 CRX HF. I got everything loose and lifted the car to remove the pivot bolt. And as luck would have it, there was no bolt head or nut for me to remove, but the alternator is still in there tight. it looks like the pivot bolt simply rusted apart. I thought to remove the alternator by the mounting braket but one of the bolts is too tight to break. Any suggestions on how to break the bolt? or how to get the broken bolt out?
