87 rollback, bad vibration in floor?

hey guys, got my rollback running and driving but ive been chasing this vibration down and im guessing i have a bent driveshaft or its out of balance. The vibration comes on at 35 mph, its really bad and you feel it in the floor of the truck, its not in the steering at all. ive played around with the rear tires moving them around, and now i finaly just got rid of the inner rear tires and just running the outers (its a dually) that didnt help at all.

i replaced one hanger bearing and one u joint was a little stiff. thought for sure that would of taken care of it, didnt change one bit. i have a driveshaft place about 50 miles from me that i think i might take all 3 pieces of it to them, have it checked out and balanced. anyone have any other ideas?? thanks!!

Matt
