What is the correct part number for the throttle cable, prop control cable, carb heat cable, and mixture cable, on the Model 76 Duchess Twin?
The listed cables have never been superseded by later numbers; they are the original and still-current numbers. Very few remain available from Beech. Alternative custom cables from ACS or similar will be the best bet. Style and dimensions are shown, to enable ordering an alternative cable.

Note that the -120 and -138 core wires are no longer available as separate parts. The -115 and -133 were originally the housings only, but the wire is now included. Also note that it is seldom wise to replace only an inner wire. The housing liner wears through, and the wire abrades inside the housing; that is what leads to wire separation inside the housing. Make certain that replacement Bowden-style (coiled-wire) housings are made with a self-lubricating Nylon or Teflon liner.
