Here is how we lift bodies for S10 swaps as it leaves the floor under the cab/frame free of any hoist legs. The chain is bolted to the top door hinge bolt which is strong enough that no sheet metal damage will occur. A test lift is done and weights added front/rear to gain level balance. Once level the chassis can be rolled under the cab with nothing in the way.
In this case a 100# tractor weight was hung on the radiator core support, Without front clip weight is hung on firewall: (Photo1)
Level cab is suspended in air ready for chassis to be rolled under it. Note chain can be seen just behind radio antenna: (Photo 2)
