84 chevy c-10

I am about to bag my wife's chevy.I have a donor fame to use so I can just swap the cab and bed over to the new drivetrain.I have heard that these trucks will lay body without a body drop.If this is true, I wanted to know what would need to be done for this, (z-ing, etc)Help on this would be great.

Z it then cut 1" - 1.5" off the bottom of the frame under the cab to lay pinch.

2.5" Z

2 & 1/2 z then put some flat angle iron or whatever across the bottom of the frame cut the floor let it drop weld it back up that way its even...To hell with layin pinch
