Here is just a single complete pit with the pit hole topper. This should fit under the platform after cutting a hole for the maintenance pit in the floor. It is the pit that goes in the back of the floor (the one that was featured in ESB).
You will need to cut a hole in the STOCK platform for this to work. One complete pit is included with this package with all the details. The pit when assembled will act as the extra support for the platform and I've allowed for it to be able to move within a full centimeter on the resting pegs so that they should work with any of the available floors that are out there as well as the provided stock floor. This pit contains 12 parts (2 interlocking walls, a floor, and all the detail pipes). I've also inluded the details just below the floor ("
The Pit Topper") that will fit just under the hole with the pit cover braces. These are where you attach the leds or EL wire to light up your pits.
