My son-in-law’s daily driven 05 GT needs a new battery. When he tried to change it, the long hold down stud shaft snapped. Now he has a stub of a stud sticking out above the plastic anchor that secures the front of the battery. Not sure what to suggest to him he has tried the obvious as channel locks on the shaft with no joy. I thought of removing the tire well rear plastic panel, but as a I recall you only can see the bolts that hold the battery tray not the battery hold down stud itself. But I could be wrong.

Suggestions would be welcome?
