yah, they get all worried.... what they don't know is that they're built better than anything today and cost less to repair!
Now, in some states, if you do "major reconstruction" you can get a new VIN number and the truck will become a "2008" or whatever year you get it registered in truck. So you could have a 47 Big bolt and if you go to the Wisconsin DMV and ask for a reconstructed title, it would be a 2008 Chevrolet Advance-Design... Then your insurance company wouldn't have a choice but insure you.... And you could drive for FEMA with it too!
BUT, it will ruin the truck as an antique or classic if you should ever want to sell it as such.... But then, if I go to the work to make it a modern hauling truck, I don't intend to sell it ANY time soon....
