I think it comes down to two questions: (1) Once the rear of the trans is unbolted and the four cross members are unbolted, what the heck is there in the engine compartment area to attach the hoist to, in order to lift the body up? (2) How ridiculously high does the body have to be lifted to clear the top of the engine?
The CAT Shop Notes suggest that using jacks alone, the body can be lifted high enough to roll the front cross member with wheels on under the front valience. It seems that still leaves a few inches to go above the top of wheels that the engine sticks up. I don't have the car at home, so I don't know how much more is needed. I guess it also would be possible to take off the front wheels and lower the cross member down further on a really good floor jack, or some sort of flat dolly.
The whole reason I am considering this is to make the job of switching my good running gear over to a new Alpine body less of a hassle. I do not know if I am making more of a hassle than it is worth. But, the idea of pulling all this stuff out at once and then attaching it all at once, sure sounds easier.
