Simply remove ~1mm from the 4 metal stalks on the chassis blocks, and also slide the lighting circuit board up out of the chassis - then file a small amount off the edges to allow it to slide down further into the chassis. Don't remove the two prongs on it that stick up, as they will support the shell. The advantage to doing this is that all the light guides will still line up exactly with the LEDs as the LEDs are moved down too. Mine now sits at the same height as the 57. I have another coming, so if anyone want's a picture guide of this in due course I'd be happy to do one.

While in there I added some centre wheelset pickups:
