best way to deal with this?

I wouldn't roll the body on its side. For me I would get a rotisserie or just lay on my back and get it done. You'll have the body up fairly high to roll the old chassis out and new one in. Plus you will most likely have other unexpected work to do after the old chassis is un-bolted.

Okay I guess i will crawl under it and the body is not bolted down to the chassis it is just set on body mounts. I have some Rust but the shell from what I found is mint it's from new Mexico
