Margaret at Mo-Ma did mention that I  needed to grind the end of the cable 
off,
so it wasn't too long.B   Didn't mention aboutB this, though.B B I can give it
a  try.



Thanks, Rick.





There is apparentally only one mfgr of all the speedo cables we get  here in 
the US. Margaret has seen failures of  her rebuilt speedos because  the inner 
portion was too long. The new cables were being made too long.  They should be 
 3/8 (Check this-I think its 3/8 -but its in my shop  manual). 
 
She campaigned with all the suppliers to get the cables made correctly  until 
she finally cornered the manufacturer. She told him about all the  speedos 
and tachs which were getting broken because the inner portion was too  long. He 
laughed and told her she shouldn't complain, it was good for her  business.
I used a grinding wheel to shorten mine, then a fine file to dress the  edge.
