Dwaine,
I have no idea how heavy the body is. Loren Alexander and I pulled the body off mine with everything intact less the front sheetmetal.
All interior, glass, doors, decklid, etc. was together. We raised the body up with floor jacks, and dropped the frame down.
We raised the rear up of body up, and while dropping the frame down, slid 4x4's under the back and set the 4x4's on concrete blocks.
Then raised the front up under the a-pillars, and slid 4x4's under the cowl resting on concrete blocks.
I'm oversimplifying, but that was the basic process. I think the whole job, from taking out the e-brake stuff, gas tank, body mounts, etc. took less than 2 hours. But Loren knows what he's doing.......
