I have used the Changeable copy with Zip change track on larger signs but have to install flex changeable copy on a large sign because the owner already has the lettering from an existing sign. I need to install the Texas Track on a 5' x 8' sign for 5 lines of 8" letters. Would like some input on how to install. I really don't just was to glue it or tape it, I also want to use small screws, anybody out there can give advice I would appreciate it, Thanks, Dawn
