I think I just take the driveshaft of and take it to a shop in Lakeland, FL. that balances driveshafts and see if they can find a problem with the driveshaft. Once I get that issue put behind me, if I still have a slight vibration and/or droning, I will try the pinion bearing in the rear end. Lastly, I will replace the tires, I guess. Good ol' unibodies and their quirks. I have owned Nash and Rambler cars since my 1941 Nash 600 (unibody) all the way up to my 1981 Concord. They are sensitive to any out of balance body part, including bad tires. I had a vibration problem with my 66 AMBO wagon and it turned out to be the tires.
