Does anyone know where I can get the correct SunCoupe top material? Mine was done incorrectly 35yrs ago with felt backed vinyl top material and it stretches like crazy especially when it is hot. Has been a royal pain and I would like finally get it done right. I don't even remember what the original material was. Anyone have an original one? Also, is it possible to remove the entire unit handle, frame and all and take it to a shop?
