Possible to swap '72 body onto 2002 2500 frame?

[comicaltatertot]

Just as the title says. I found a 2500 truck for a killer deal $2500 for the whole truck, it has 271,000 miles on it but I would be rebuilding everything anyway. But how possible is it to swap the '72 onto a 2002 2500 frame? I know that a bit of fabrication would be necessary. I was just wondering if it will work. Any advice would be appreciated, thanks.
