Here is how it went down...I tried to copy the instructions listed on the Blazenoffraod site (a link back to CK5), but realized that dude only has one floor, his sub floor is totally gone...Had I to do it over again, I would have cut the rocker below the door line adn welded the slider in there. As it stands, I cut out the entire rocker (just like the instructions), welded in the slider, then, cut, bent and smashed the sub floor into place and welded it to the bottom of the slider...plenty strong.
I posted this in case anybody else was about to do this, thought it might help.
