Hey All, 65er here again! Was hoping someone could shed some lite on this Vibration issue with my 65 base model. It feels like the tires are out of Balance between 30 + 40mph. smooths out to 50 then starts again, Motor has been replaced and is New, Trans and driveshaft have been rebuilt and has new Tires! To my mind, the only thing left to consider is Wheels and Axles! Any thoughts would be helpful! Thanks.
