I just bought a grain truck from a farmer and he was the second owner of this truck. I paid him, he gave me the title and I loaded it up drove home. But I cant find the vin any where on this truck. I know it isnt stolen because it came from an honest man and he really doesnt remember where it is. They changed engines when the 216 broke its crankshaft years ago and replaced it with a 235. Any help would be appreciated. Where do I look?
