Hello Joe,
Email Electric Dreams and ask them. They are very active in the North American slot car world and are have contact with many clubs.  
There is a group known as "Norcal Slot Car Racing Association". Their web site is fairly quiet but they list four clubs here -   https://www.norcalscra.com/contact.php 
One of the reps from the Modesto based "Motown Raceway" appears regularly on the World Wide Slot Car Chat.  This is a Zoom chat and is published on Youtube.  You could ask on there.  https://youtu.be/56yD4Fgws04?t=803

Hi Leo,

I've contacted them but, thus far, no reply. I may give them a phone call later in the week. 

Joe
