We have a unique, and quite nice, Corvair Rampside topper that appears to be made by "Cross Country." I have no idea how many of these were made, but it has to be quite rare and this one is in really good shape. For more information, please call Chris Shade at (402) 460-7097. Be sure to learn more about us by checking out our website at www.shadesclassiccars.com -- Thanks!
