Hello to all. Just aquired a 57 6400 and need lots of help. I solved wheel problem right away. After reading all the posts on widow makers I put out feelers and found 22.5 inch wheels. They must have come off an old u-haul truck becuase several of the tires say property of u-haul right on them. They are tubeless and made by acuride wheel company. Interesting right next to the acuride stamped logo they also say firestone. Tires are next. Any recomendations on size? Also need to rebuild front end. Need spring end bushings for sure, maybe tie rods and king pins. Where to buy? Also is the cab same as pickup? Need alot of small parts, weather striping etc.
