Lol. I’ve done crap like that. Put trucks on frames of other trucks. Made trucks from other trucks. Made cars from a combo of cars.
A friend got his Camaro t-boned in a wreck and sold it to a guy I know. The guy who bought it wanted me to rebuild the engine in the wreck and put it in his car. Then take the drivetrain, trans and rearend out of the wreck and replace his. My friend had a shift kit in his tranny and a 12-bolt rear-end in the wreck.
Then another guy wanted me to take the body off his Pontiac and put it on another frame. I think I rented an engine host to do that job. It’s been like 15-20 years ago since I did that job.
Maybe get everything loose, rent an engine hoist, lift up the body in the front, block up, then the back, block up, then roll away frame. Now that I think about it, I think I used a big oak tree to help do all this. i got it done somehow.
Hey, that’s how to do it!! “somehow”
