How to install glovebox??

I just replaced the one in my 67 Dart last week. I wish someone had told me you could fold the sides in. It would have made installation much easier. I was able to get it in without ripping, tearing or wreaking the new one. I just need to get one more screw that I did not know I was missing, otherwise it's in, just need to do some small adjustments to make all the sides sit flush.
