I live in San Diego and want to buy a 1965 Chevelle. I was a little concerned about saftey. Has anyone had an experience? Am I pretty much dead if I get into an accident? I know the cars only have lap belts and no head rests. Could I swap out the seat and maybe put in modern day belts. I would keep the original parts obviously. I am a purist when it comes to originality, but I don't want to sacrifice my well-being for it.
