3B is right. Most or the parts are the same as the 55-59 task force pickup trucks. I prefer the narrow radials for my 2 tons. There are still some 9.00X22.5's out there. As for the rear, the 10 or 11X22.5's work well. I don't know my metric sizes. I have been able to get my rear tires from the local school bus barns for free. The suspension parts are a little tougher to get. I have had the best luck finding donor trucks. Good luck, sounds like a fun truck.
