I should look at the instructions, but as I recall, when you cut off the molded marquee that then leaves space for Miller sign once you cement the top and bottoms to the front section. (I used a razor saw) I have not glued my sign in place. There is enough tension (or spring) to hold it in place. But you could use a goop glue or painters tape at the inside corners. I tear stuff apart too frequently, so try to avoid more permanent fixes.
BTW - my photo shows a white frame around the ticket taker - it is solid black - must be a flash reflection.
