Today I double checked my template and then cut out the relief areas in the sub panel. I set the panel front up right in a table and slid the glare screen over the top to check the fit. One area needed to be trimmed 1/8" more. Once done, I again slid the glare screen over the top. Fit great. I was really happy that the screw holes lined up with my panel too. I installed 4 screws with plastic washers to secure the panel. I then rolled the panel over on its back so I can start to work on the bottom side.
