Is this the wrong glovebox liner?

I just put mine in and it's a cardboard one.You need to take the latch off of the top, take the glove compartment door and hinge off as well. I found that if you collapse the sides where the bend marks (scores) are, it fits okay. Ya just need three hands to pull it in place. #6 or #8 sheet metal screws will fit the metal screw hole tabs.. Oh by the way, mines a 73 too...
