Was able to figure out how to replace it from googling it (the mysterious part). Thanks to all those folks. I did do it without loosing the little button that some do knock off which then pretty much renders it useless (one of the Evo 2's only downsides...). It works as a good replacement, dark and scratchfree since most everyone gets scratches in the center from using the sun shield in day-to-day use. I do now have to exert much more pressure on the slide lever on top of the helmet to make it work. Recommend? Sure, because there's no other choice :) just be careful on replacing it.
Fit and finish appeared without flaw. Replaced easily. Have ridden in a wide variety of lighting conditions. This dark/mirrored shield combined with the dark sunshade and my use or not of sunglasses provided a wide array of options. I even wore it for several hours on a rainy night to get home since I left my clear shield at home. I would not recommend night riding with it but at much slower speeds and increased focus it can be done when there's no choices. In all other cases it was outstanding and overall I do recommend it.
