Re: Tub removal - no idea what to expect.
Pretty simple process. Make sure you've got everything disconnected as the other have said, and have whatever tools you may need to disconnect what you miss easily at hand.
I lifted my body off by myself with a come along rigged to the rafters in my garage. lifted rear end first and set it on some sawhorses. then lifted the front end and rolled the chassis out from under the body. I lifted the body off over both the shifter and the steering column. When lifting the front end it was lift a couple of inches, roll chassis forward a couple of inches, repeat process until I cleared the steering column.
