Stock Floor Questions

sooooooo, im thinkin about keepin my truck this winter, but want to stock floor it.

Does anyone have any good sites with info on how to go about this process......i know alittle about the SFBD process, but would like to learn more. Ive done a traditional bd before, but never a stock floor.

im just curious to what everyone does as far as cuts......do you leave the engine and tranny on the frame when you do it? what do you make the new frame out of? just bassicly a good run down on how its preformed.

thanks
