I jacked mine up on the crossmember so the tires were 3" off the ground and locked the door behind me. It only took overnight. In fact, it spread out TOO far.
If you've got a portapower you can put it on the shock tower caps and push them out till the piece fits.
My project now is to repair the shock towers that are totally destroyed. I pulled out the engine last week and I'm all fired up to finish that and the torque boxes.
