Inner rear enders on 50-54 panel or suburban

[48fordf1]

Im wondering if anyone knows where you can buy the inner curved fender metal that you see in some early chevy truck beds. I have a '52 panel that the previous owner cut the inside rear fenders off of. He then pretty much "tubbed" it out on each side due to how they mounted the coil spring mounts for the rear they installed. I ripped out the coil springs and put in air bags. So, now, i want the inside of the bed (enclosed body) area to look original with the curved inner fenders. And a beautiful wood floor. I was thinking someone sells them for different model pickup truck beds and that might work. Maybe someone has a donor/parts suburban or panel and would cut the majority of it out and sell them. I dont know. Thanks for any input.
