Installed mine tonight and I didn't need to remove the top plastic as you did to get the old speaker panel plastic off. It just slid out from under the keeper and I slid the new one in. I think it took about 10min to do the whole job but great work on the tutorial. What an amazing upgrade to BSD it made a huge difference. I also didn't remove the standoffs that hold the screen back a bit, I might change that but it still looks great as is.
