Also, the one that helped a lot was this homemade (found lying around the basement) 18" copper tubing used as a breaker bar. Actually, it would have been more convenient if it had been 3-4 inches shorter, but it worked just fine. The basic 3 -ton jack and two stands help to prop up the rear of the car to get to the headers and give you ample space to work underneath the car.
PLEASE REMEMBER - SAFETY FIRST!!
BTW, here's a blurry picture again (sorry) of a post-dremel nut extraction. BTW, did I mention, in my frustration

prior to receiving my new dremel, I took a power tool to it. :troll:
