I had the same problem as you. I had a bed, and didn't/couldn't find a 4x4 bed so I found these flares for sale on this forum.
They were NOT cheap. I think the guy wanted $300 for them, but hey I haven' t seen any since.
These are from a 4x4 Mazda pickup. And, they DON"T fit unless your willing to cut up your existing fenders, like I did. {Front, and back}
Then you will need some plastic to metal panel bond as these things don't have any lip, or flange to screw into the bed, except for about two on the front, bottom, edges.
Hope this helps.
