[TR] Missing parts of an Angle Drive

[John Mitchell]

    On a long drive last weekend, my speedometer suddenly stopped 
working, so I figured a cable had broken.  Tonight I checked and both 
cables(1976 model) are fine.  So I then figured the cable inside the 
angle drive had snapped.  When I pulled it off tonight, all that was 
left was the housing.  The internal parts were missing.  Is the inner 
mechanism pressed into the housing or does the set screw hold things 
together?  I had always thought the set screw just held the part 
attached to the cable from changing angle.  Does that screw need to be 
snugged after installation?  Thanks for any insights.   John Mitchell
