Ikamper Accessory rail help

Hey All, i have a GoOverland expedition, and I recently bought an Ikamper accessory that slips into the accessory rail on the skycamp. I was hoping to find the rail or a third party equivalent to add to my tent. Does anyone have there Skycamp open so they can get me some dimensions off the skycamp rail? It doesn’t look like ikamper sells the rail as a replacement part yet
