The problem ( if it is a problem ) is that the inner coating on the acrylic sidescreen gives it a slight tint, hence when the coating is polished through the polished area shows as a lighter colour. Using a non MMC variant It will look weird having one screen section clear and the others with a slight tint, unless of course all 4 were replaced with non manufacturers versions. The original fixed forward section of sidescreen is printed on its front forward edge with V111/A/M then a E5 within a circle and finally 43R-00062 I assume these indicate the spec and part number for whoever produced it?.
