There is a slight difference in the arch. I do not recall exactly what it is and I'm not in the office at the moment. I also don't remember which color goes with which gasket. I can look tomorrow and find out. It is possible that the gasket is mis-labeled but untill I look at the ones I have in stock I can't say. I also stock the current pan and I can set both gaskets in it and see how they fit.
