Hello Brian, welcome to the wonderfull world of SSD. My track is also in a similar way raised to the ceiling (4,88x1,22 m.) I noticed your unusual place for the powerbase. I made a cut out in the border along the long straight too be able to position the PB there. Have the same problems as you, It's so damn small ! Does the track run well, can't see wiring for powertaps or LC's.
