I would love to see how you have all these jacks and stands set up from different angles and the step by step process of how you move the frame into place. Can't wait to see the finality of this.
Did you see the album link I posted? That has a lot of pics I haven't posted in this thread.

I'll be taking a lot of pics on the way in. The way out was sort of spastic, as I didn't KNOW how to do it; I had to invent it as I went along and there were a lot of false steps--so I didn't take a lot of sequential pics, but there are some. Even doing it right, it will be a LOT of moving the rear support around, and up and down, to thread the needle with that frame. The front stays in the same place, but also has to go up and down on the way in because of the profile of the frame and where the fixed low and high points are. It is VERY tight and the missing rear control arm bracket helped on the way out. That has me a little nervous, but I have a backup plan in case that won't go past the crane leg. It will be close.
It's just four six-ton jacks on the body corners just inside the wheel wells, and a normal engine crane holding that up by a chain. I used big deep sockets on top of the jackstands to spread the weight along a larger contact area on the sheet metal. As far as I can tell, nothing has been hurt so far. The jacksstands are staggered slightly so they don't align with each other side-to-side. This makes it easier to maneuver the body brackets past the jackstands. It's tight sideways, too. (Yeah, I know, "that's what she said.")
There are some decent pics of the transverse steel bar holding the transmission, which is supported by two three-ton jackstands. The metal bar is a side rail from a metal bed I saved for a moment like this. There is very little weight on it. It's just to move the back of the trans up two or three inches; things are fine without it there but the trans gets in the way of the frame going by.
The whole thing is solid; I tried as hard as I can to push it in a few directions and it just won't budge. My driveway is 80 years old and been repaved over a couple of times and it is seriously solid for asphalt. Never had a jackstand try to tip even at 100°F+ and I've been wrenching out there for almost fifty years. Even so, I would not go under on hot days. When I did, I set up my big logs as extra protection. Even if you tip a log, it's still thicker than I am. Useful things, logs.
I really didn't have to go under much at all, once the jacks had been moved from the frame to the body and I liked it that way. Everything to disconnect (and reconnect) was/will be done with the frame on the jackstands, not the body on the jackstands. However, to treat the underbody rust, I'll need to get under some.
