Under bed gas tank relocation

[craigg1]

I've decided to relocate my 1968 C10 behind the seat gas tank to underneath the bed. I have seen many different options available and also many threads discussing this. My question is, is there a kit that doesn't require welding? Also prefer the kit to have everything needed and will allow me to just come up through the bed (flush, not sticking up to far) to fill it? Looking for simple and easy.
