radianrider - Well the '55's were born without seatbelts. My guess is they installed them after the law came into affect which probably means they only had belts in the outboard positions, probably not in the center. However, I have heard the story you mentioned more than a few times. Cars from that era were famous for being the breeding ground for a couple's first child. Reminds me of something I heard as a kid that has stuck with me ever since, "Life is sexually transmitted."
