I have a 1987 Tournament 19 and a previous owner replaced the original window with plastic... The walk through window is the oem glass. I want to replace the left and right pieces as they are discolored and not a good fit.Water Bonnet the oem manufacture of the windshield is not in business and that makes it difficult..Does anyone in cyber land know the dimensions of the glass, know somebody who does or have any suggestions??? Thanks for your help.. Barry
