Problem solved! My shift cable fell off yesterday morning while backing out of my driveway... not a good start to my commute. I was able to rig it using zip ties to get it driveable, but it wasn't a permanent solution. I went to Advanced Auto Parts and found this! Part # 14041. This bushing pack is an exact fit for these trucks (mine is a 2004 Fx4 with floor shift). The correct bushing was the only one with a part # on it and it said "China". It snapped right in and it was fixed! $7 is much better than buying a new shift cable!
Hope this helps!
