This is so simply I'm almost embarassed to ask. On my 70 Roadrunner front bench seat - aren't the center belts (the ones attaching to the tunnel) supposed to go THRU the lower seat upholstery as opposed to just lying on top of it? The belts have a plastic grommet bezel thing and I'm about ready to stick a knife thru the new seat cover but... I'm sure someone here has an answer and/or photo to help me out. Thanks in advance... Mike
