I want to install the dash pad as it was originally, I have a new dash pad but it has no holes for screws on the front. I have several books on restoring mustang but they say different things. One says there is only one screw over the glove box in the middle of the dash. Another says that there were four screws just over the glove box. I see four holes over the glove box where screws could go, but which one is correct? Or are they both right? And is it the same for the drivers side?
