Indiana isn't real hard to get them registered so long as all of your paperwork is correct. You will be asked what weight you want to register it at and the cost is based on that. If I remember correctly, 11,000 pounds is the max weight you can register to get the "antique" registration . You will have to send in 3 photos of the numbers painted on your truck. One from the rear and one from each side. Can be on the outside of truck somewhere or inside the doors for the side numbers. You will still get a plate when you do it that way, but you can keep the plate with the registration in the cab.
