Aftermarket shoulder belts for 68 barracuda convertible

Crumple zones or not I think that although not perfect I would install and use shoulder belts. That being said, I saw a neat trick that one of the guys at a car show had done to his convertible to have shoulder harnesses. He secured a chain using his rear seat belt bolts ( probably had to bolt a plate in under there between the upper and lower cushion ) and attach a chain to that. He then attached a seat belt to it and had a receiver at the front to click into. When he would get to a show he just uncouple the belt from the chain and hide the chain between the cushions. You could I suppose use a cable instead of a chain. Trust me, shoulder harnesses will add protection to a huge degree rather than not. If anyone questions that they are free to do what they feel is right for them, but me it's gonna be put them in. There is no downside. Watch the video of the 1300 HP Mercury crashing at 45 mph on YouTube. The were prepared for impact and still flew forward like ragdolls. To anyone with an old classic I would recommend installing and using shoulder harnesses no matter what you drive. There is no downside.
