If anyone gets to this before I do, be sure to mark the orientation of the flange/u-joint so you can return the D-shaft to the original postion; its balanced (for 100 MPH?). GM tried this "full time 4WD" ~30 years ago on the K5.

Scrap the idea removing the front D-shaft. Because of the diff in the T-case, there is no 2H mode, yet.
