Tracks USA sells the kit for it and its only 400 bucks for the track, the rail extensions, and the tunnel extension.
Is there anyway to bolt the extension on the ride it a bit to let it settle then weld the rail extensions in place for extra strength? I can weld aluminum so im just wondering if that would be an idea worth considering.
