I can say that heat does wonders for freeing steel bolts into aluminum.
The different characteristics of the metals allow the heat to break that
"bond". If you can get the stud cherry red and let it cool, you should
be all set. If you don't have vice grips, you could grid some flats on
the sides of the stud to get a better grip (or to use an open end wrench
on. You might even try the vice grips before using heat. Anyone else had
problems with doing this?
