DRIVESHAFT issues

1968 plymouth barracuda 440 8 3/4 rear (SUREGRIP)

i recently started to drive my Barracuda (daily driver) work and back home about 20 miles round trip daily and started to notice the vibration.

recently did the SS suspension on it and thinking the angle might be off but took a quick look and angle is actually really close to straight. started to think it might be the u-joint then took another look and saw that the drive shaft where the u bolts clip on do not align compared to the transmission side the pinion side is about 15 degrees out. is this a bad drive shaft?
