You’re in the custom fabrication realm of this hobby. All I can say is the bedsides are correct for your truck and it looks like the back support is not from a 47-53. The supports under the floor don’t look like my ‘52 and most likely came from the same truck as the floor.
Here is a photo of the rear bed support sill from a 47-53 Chevy/GMC, looking from underneath which should help in fabricating new supports.
