Want to raise my bed floor only..looking for guidance

Anybody got a a tech article on raising your bed floor? I am not doing a body drop, I just dont want a notch cover or a gaping hole in the bed floor. I done a search but didnt really find out a step by step procedure for doing this.

I know in mini truckin mag a few issues back they did the bed on a s10 with step by step instructions and pics. Same concept different truck.

Here ya go. Looked it up.

Thanks. I got that issue here somewhere.
