Could be as simple as the balance or wear on the tires. You say you need tires? Even if you don't consider balancing them. Also the driveshaft could be out of balance. Also if the tranny has been swapped the driveshaft could be to short(spacers are available) if this is the case you'll be able to see marks on the front yoke where it was further inside the tranny at one time. I had this issue when I swapped trannys.
