Aftermarket shoulder belts for 68 barracuda convertible

I agree. I cannot believe that both the owner and the presenter let it get to the point of endangering the public with THERE decision to continue on. If there are shoulder harnesses available I wear them no matter what. When I was younger I looked inside a car ( 67 Fury) that had hit a pole to where the headlights were actually "looking" at each other. There were teeth broken off in the steering wheel. That told me that the driver was most likely belted with no shoulder harness and his upper body pivoted forward. I assume he probably was killed even though the damage to the car looked like a survivable crash. From that point on I realized that seat belts alone offer only very limited protection and even though our classics are no match for what modern vehicles offer, shoulder belts add an exponential degree of added safety. Just my 2 cents.
