Hello All,
Just for the record, my 64 Imperial has seatbelts front and rear. The are color coordinated to the interior. Unlike the belts of the 70's -- mine are "aircraft style". This simply means that there is NO provision for shoulder harnesses. So you end up with a "lap belt". I never really undestood what these were supposed to accomplish? After all, in an impact the body will continue in motion. So your head still goes through the windshield.
