Same guy. Cliffy. It screws down where the wireform attaches near the catapult. Uses the same screws. You just take off the ramps, take off the side rails, lay it down, attach side rails, attach the ramp right on top of it.
Oh, and btw, I have a CRAAAAAAPTON of teardown pictures from shopping my STTNG recently..I'll send you a link when I get them uploaded...it's a beast lol.
