LS1 Aluminum DS
Along with the Moser 12-Bolt, I decided to upgrade to a better driveshaft too.  The stock steel driveshaft is only 2.5" in diameter.  It isn't well balanced, and vibrates like mad at over 90 MPH.  The LS1 Aluminum DS is 3" in diameter and is much better balanced.  It also weighs less.

This DS is a direct swap.  I purchased it slightly used for a good price.  I had to swap out the U-joint with a Spicer/Napa 447X so that it would work with my new rear end.  So far, it seems to be working out pretty well.
