I had good luck with sazall
Just pulled 40 off the frame. I tried cutting torch. Seemed to set the bushings on fire and didn't really get the bolts out just made a big mess. I got a few different size blades and sawed out the bushings then through the bolts. If you try to get through in one shot the blade will bind on the rubber. Some were best cutting free from the frame, then cutting the remaining bolt off after the body was removed. 4" and 4 1/2" grinders got me knowwhere. Dremel tool was totally useless.
