Mine wasn't that flimsy but it did sag a little, if you add a cargo strap down to the front bumper bar to give some support when your lifting the body off you can keep from sagging and you can adjust it to ride level. I made some adjustments to the body dolly plans and overbuilt it, it's kind of personal preference thing, get the biggest casters you can for it so it will roll around easilly. The front will sag a little if unsupported but not bad. If you drop the gas tank you can decrease the amount of travel needed to lift the body. If you have a good engine hoist you can get by with that but I don't recommend it unless it's a big'un. I lag bolted a wood header up to my garage ceiling with some brackets and used a chain host and it worked out realy well. I could pick the whole car up with it, (don't ask)The hardest part will be those pesky rusted body mount bolts, you will have at least one of those suckers to deal with unless your really lucky(cross you fingers). Once you get it off start taking pictures of everything, and I mean everything, it really helps a lot when your putting it back together. One of those plastic bin organizer makes life a lot easier for the bolts and nut storage.
