Question for you guys: I'll be cutting the sheets to fit the holes so to speak. What is the best way to install the glass patch panels? For the console, I'm going to use some scrap plywood, and on the front, drill through the console and the patch panel, using the plywood to hold the panel flush. At that point, I'll tab it in from the back. However, I will not have access to the back for the rear storage area. What is best practice for installing the panels where there is no access from behind? Should I consider installing butt blocks? Any insight is greatly appreciated!
