This would be best a do it yourselfer or find a shadetree mechanic to help. Hope you have other transportation 'cause this will take awhile.
Maybe you could have some braces welded on .

Removal involves a forlift or overhead which to swap bodies.
You have to disconect fuel lines , brake lines , unplug wiring harnesses ,,, etc. etc. ,,,a cherry picker to drop the engine in ,,transmission jack ,,,, alot of stuff,,,good luck,,,I hate rust...
