Go with lr2001. They are quality. Driveshafts are something I wouldn't leave to chance, like brakes.

 

There is some chance you could rebuild that one have have it work, but why take the chance? You know there is damage and have it apart now. The cost of having it break is way too high. Buy the new drive shaft and establish a strict schedule of maintenance.

 

On my phone so can't see the photos well. If you have any concerns replace the double yoke or the entire shaft. A number of people on the forum have replaced their propshafts so you might find the part cheap. A complete shaft that needs rebuilding (which all unknown ones do) is worth about $50 if on good shape.
