Rear driveshaft slightly clocked, cause of vibe?

I've been hunting a pulsing vibe that phases in at 45mph then fades out then comes back in at 65. Took the rear driveshaft off this morning and drove up to 70 with no vibes. Got back and started looking the DS over closely, all U joints tight, slip joint tight, the ball joint thing in the center of the DC seemed a bit sticky but tight and not bound or notchy. Looking at it sitting on the bench something looked off. Got a flat piece of steel to sit on and my level and discovered the rear U joint is clocked slightly out of plane with the flat on the DC joint. It's obvious eyeball sighting from the U joint to the DC joint, the photo shows amount. My digital angle finder calls it 2 degrees out of plane. Can this be corrected?

The other end of the level is sitting on the machined flat of the center part of the cardan joint that should be perpendicular to the bore of the u joints.

I rotated it 180, still the same.

No idea who made it, was asking if anyone recognized the labels on it. Over 10 years old for sure. I've never had driveshaft work done on anything, so something like this is fixable?

There's a good driveshaft shop nearby will see what they say.

I would not waste my time cutting that shaft apart for that minor deviation. That ujoint missing the dust seals should be addressed and have the shaft checked for straightness(runout along length) and balance would be a good thing.

That's why I posted, got no idea what tolerances are for a driveshaft.
