I have been through drive shaft vibration on a 1978 Chrysler and found that there is a prescribed "Maxium" angle from the CL of the output shaft on trans to the slope the shaft makes going back the the pinion flange. If your rear springs are sagged a little bit you could be right on the verge of too much run out.
