E-27 Shift cable

Having some problems with the shift cable on my '77 E-27 W/ A4. I understand Morris is no longer making this cable.
Does anyone have imformation on a source for the correct cable, or what might be adaptable, if proper part turns out to be N L A.

Thanks,

I replaced the shift cable on my E-29 in 2000, and another E-29 owner in my marina recently replaced his shift cable. In both cases, we used Teleflex-Morse Red-Jaket (that's really how they spell jacket) cable, 12 feet long for our boats with A-4 engine and pedestal steering. We removed the old cable and used the numbers printed on the outer casing to determine the cable part number. We didn't have any problem with availability. I checked, and BoatUS has Morse cables listed on page 643 of their current catalog. I don't have West Marine's catalog handy, but I think they are even more thorough regarding cables in their catalog.
