Hi Anthony, there have been a few threads on this previously, including at least a couple of pics different members have posted showing their home built lifting apparatus, from memory somebody even built a carousel.... cant remember who. If you trawl around using the Advanced Search Bar for long enough you should be able to find these. Some members seem to have used both the rear bumper bar bolt holes in combination with the front door hinge bolt holes. I dunno never done it, but I'd advise caution against using a sling though, unless you really have no alternative, or you're experienced in operating them (perhaps you are, I dunno).
The thing is, once a sling takes tension, the points it presses on the body change because it will try to form an apex to the hook you lift from. Its very easy to bend the side panels or press in the curve of the roof above the gutter. The sling finds it's own shape as it tenses and you can't see it until it is happening and then its dented before you can say "stop". There's no reaction time with a sling.
(I used to work for a recycler with a ten tonne lifting crane, when we needed to lift a "good" car the sling was used, it might look soft, but once under tension it's as crushing as a press. I've seen slings dent a lot of panels (including the roof on one side of my sandy as described above... this was an experienced operator who chocked it carefully with polystyrene to avoid this, "It should be ok" he said... I checked it with him again and agreed.... hmnn, I was very annoyed with myself two minutes later). Sure we could've built a trapezoid frame to sit inside the sling but its got to be rugged, the tension is surprising, and if it collapses, or the sling slips off it worse damage and you need a pretty large sling (remember the top of the sling would form a hard straight line over the roof if you create two lifting corners, if it pulls up lower than the roof line it would deform the roof all the way across in the blink of an eye just on its own), I wont ever be mucking around with slings on good cars again. Almost always I saw a panel dented somewhere, and they are very good at making full panel dents and stretches. However, perhaps you are more experienced in their use than I.
Anyway, in terms of finding those threads I had a very quick look, these may help for starters, but there's a fair bit more on the site see for starters;

Body removal, and chasis restoration. http://www.mysandman.com.au/forums/s...ight=body+lift
Also at a quick search I notice this current thread follows on quite neatly from another you started on this subject. Could I make a suggestion you ask a moderator for a thread combine before this thread gets much longer, it might save some work for moderators way down the track? See;
Lifting Body of Chassis http://www.mysandman.com.au/forums/s...ight=body+lift
Anyway, I'm sure you'll work it out, the most important thing, I think, is working out a plan that lets you keep your head, hands and the rest of you out from under the load at all times as you design the lift and suspension stand and how the job will go. The vehicle is always repairable if dropped.
