I dropped one into the the LCA once too. Honestly, I think this was worst then having to cut them off. I had to spend like an extra 2 hours wrestling the lower arm off to fish it out.PB blaster works best. let soak for a few min, then once nuts removed hit with hammer. be careful the camber plates fall. i had mine fall into the LCA
Before cutting them off. Try soaking the bageezers out of them and let them sit at mentioned above. Then before you try to loosen them, try tightening like a 1/4 turn or more. This way you may be able to crush and loosen the corrosion between he parts and set them free.
