Does anyone know if someone makes a reproduction rearend inner fender for the stovebolt era Chevy Suburban/panel?

I've seen pics of these and would like to use a set of repop or original fender, if i can find them, to create a small tub in the box of my 1954 Chevy 3100. From what I saw, I believe they match the bends of the original bed side stamping.

thanks!
