this is want my friend told me. it will need modification and will not bolt right in.
You take the "feet" off your stock rails. The pegs that bolt to the floor. Cut them a ways back so that it clears the hump in the floors.
Now, you have a shop measure out the distances and weld a box shape of square metal tubing. The feet should end up being welded at each corner.
Next, weld the rails in the center on the two bars going like this = each side on the front and rear of the rail. Bolt the whole thing in, and voila.
It will sit higher though.
