We appreciate your patience. The Cox number you have provided to us could either use our 23-070 concave wheel or 23-081 convex wheel. Look over both wheels to see which would make a good match. The top Cox guide that is usually used with these rollers is the 23-090 and for the track, our 23-245. Review each part at your leisure and if you should need any further help, upload a few photos for us to take a closer look.
