I completely agree. It's problems like this that Ford lets go on and on that makes you wind up scratching your head. My 70 Boss 302 was the first year for the shoulder harness style that was engineered to be put back into a paper clip in the headliner. I mean who thought of that? Then with the Fox body, Ford came up with the bright idea that that the seat back should have a plastic guide type holder (that is useless by the way) mounted to it. Again, who thinks of this crap? This guide thing has continued on for 25 years! Doesn't anyone at Ford sit in their cars and drive them? Ever tried to reach back for your seat belt while driving to buckle up? It's like somebody must have stole my seat belt cause it's not here!
Sorry for the rant, but this issue has always bugged the crap out of me.
