Brio Sky Train/ Skytrain Supports Clock Tower 2003 Tram

I am looking for accessories and main supports/ risers for the Brio Wooden Sky Train monorail system (2003) - also known as the Skyway Tram. I am interested in the small and large Sky Train supports ($12 per pair), the Clock Tower ($30.00), the Stop and Start Auto-track ($25.00), the Loading Station ($30.00), and any other accessories from this line. I will consider other prices! Thank you!
