this is what i went with; and it didn't work. the holes i drilled based on registering them this way ended up a good millimeter on the wrong side, so pulled the neck away from the body instead of tight to it. got around it by drilling the holes in the body to a larger diameter (they'd been drilled to 4mm on the supplied body, i drilled mine out to 6mm in the end) as the screws were grabbing too much in the body and not enough in the neck. maybe the screws were grabbing in the oak much more than they were in the softer supplied body,
i also got the router out and stepped in the cavity at the back, and then hand shaped a piece of the same wood used for the front of the body to fit. planing a piece of wood from 21mm down to 5mm was fun.
