My new CruZin windows design will be available before the end of January. The window now fits snuggly into a polished extruded aluminum base and does not have screws that penetrate the window. The mounting pins slide in a track that allows them to be placed anywhere along the base. The pins are also aluminum and can be easily bent to allow the window to be tucked in closely behind the windshield.
As soon as they are available, I will update my website with new photos and ordering information.
