Ok, I have a couble of body bushings out already. The ones remaining are the top of the back fenders near the springs and the 2 at the end of the doors. If you have to cut access, where do you do it?

from directly above the nut cut a square out and the nut will be accesable

Look for a convex dimple above the area where the bolt comes in from the bottom. This small hump will be aprox 1-1/2 inch in diameter.
