1972 Dart Headliner board install.

Okay, so I went to install the headliner board for a test fit before I covered it, and I got one shoulder belt bolt in and I was about 3" too narrow to get to the other bolt. So I thought the holes were wrong, so I lined up the visor holes and looked at it and it looks like its narrower and shorter,,,, did I get sent a dart sport headliner?!? I bought this thing 2 years ago...... crap!! Any thoughts?
