In 1985 I ordered a S15 pick-up, my first "new" vehicle. GMC had some deal going where if you died in the truck, and you were wearing the seat belt, they would give your beneficiary $30,000. I figured what the hell, why not wear em? I've been a loyal seat belt fella ever since.
Since then I have installed belts in my '31 Model A Tudor, '27 Model T RPU and '65 C10 SWB SS.
