Fixing holes cut out in my bed floor?

[Crazy-J]

Are there any options on fixing the steel bed floor on these trucks? The previous owner installed a fuel cell but cut two holes in the bed of the truck. He then installed an aluminum panel over the top of the holes. I installed a JAZ fuel filler neck that comes up a couple of inches over the top of the bed floor. This whole setup is pretty ugly and I want to do something about it.

It looks like no one makes a new steel bed floor and I haven't found any trucks that still have theirs in good condition. Is a wood floor the only option I have to de-ugly my bed?

Also, any options for the fuel filler? It had just a wedge in it before which was a pain in the butt. Does anyone make a way to hide the filler behind one of the taillights like in an old Bel-Air?

I'll take a picture of it when I get off work to give you all a better idea of what I am working with. Feel free to post pics of what you did with your fuel cell filler and bed if you want. Thanks.
