I know I shouldn't get involved, but i will as usual. Longhorn is right about several things. The actual Facts are that you cannot under any circumstances modify safety equipment on a vehicle. That is a FEDERAL issue. Now, do we do it, sure, for the sake of making our vehicles safer. And yes it is illegal to add seat belts to your '47. The local police would love to pull you over for not having seat belts, but they would not be able to make a ticket stick due to the fact the vehicle never came with it. Yes if you add newer seats with integrated seat belts you are breaking the law, (that is why we reinforce the bolt holes when we do this). It is allowed due to the "off road use only" clause applied to nearly everything aftermarket. I don't think anyone is saying your going to jail for it, but the fact is it is illegal. if anything (god forbid) ever happened with that child seat in an accident, the child seat company would not be liable for anything even if the seat failed due to improper installation and unapproved anchor points. And just for the record, I think gas weighs near , 6.5 lbs/gallon (I'm a fireman, I have to know hydraulics) which equals roughly 130 lbs+ tank. figure 160 lbs total, across 8 bolts, with the structural integrity of the tank distributing the weight across the bolts, your looking at 20 lbs per hole. Now I know if you put a little wight behind it you could definitely bend that thin sheet metal by pulling on it. I think you have a great idea and since you put extra metal behind it, that makes it a little better. I'm not saying your wrong, but I think Longhorn man was trying to give you a heads up about the dangers involved in what you did. After all his posts, he knows a thing or two. I think he was just trying to help you out. Like I said, if it gives you a warm and fuzzy, then by all means do it. Just be aware of the possible reprocussions (spell??)
