I did much the same as above but I used an engine hoist. After removing the front clip I used a couple of holes in firewall to attach a small chain. The chain fit into the hook on the hoist and then lifted body away from chassis. If you lift from the side the hoist gives you stability with the "legs" under the chassis and has much greater height capabilities. Once you put front on some type of stable platform move to the rear and repeat the process. I used two sets of Steel sawhorses and 4x4 beams as the platform. Good luck, go slow and be careful.
