Bobby Kent asked, "Does anyone have any idea how to put a stint in
between mashed segments of the tubing (what to use and where to get
it)".  So, I shot a short video and posted it at YouTube.

In the video, I demonstrate the two most popular methods of repairing
crushed trackerbar tubing.  The brass connectors and rubber tubing
that I use in the video are available at  http://Player-Care.com/ 
The video is located at  https://youtu.be/ljwXVmfP52A
