Armored Cable Replacement - 1947 Packard Custom Super 2106

Hi Everyone - I'm having issues with the armored cable in my Packard Custom 2106. Frayed wiring caused a short and now I'm looking for advice on who might rewire these units or an NOS/Rebuilt replacement might be available and from whom. I've tried most of the vendors listed in Hemming's that do wiring harnesses, but no one wants to touch it.
To prevent the car from being hot-wired, this cable has the ignition switch at one end and moves to the coil. Autolite and Delco were suppliers to Packard and this seems to be a Delco unit. The cable itself is heavily enmeshed with steel wiring to prevent people getting into the unit. It's about two feet long and snakes from the cowl mounted coil through to the dashboard and the ignition switch.
Pictures are attached.

Any suggestions on where I should be looking to get this repaired or replaced?

Thanks!
Dave

You might check with Max Merritt Auto. It has been reported by others that the wire was replaced on some rebuilt switches they supplied. I don't know if it is only on his exchange switches or if he would do it as a service. Removing the armored cable can be done by splitting and then repairing the crimp attachment to the switch body but the terminal the wire solders to is well recessed in that small opening and somewhat hard to access even with the armored covering removed.

This is probably a dumb question, but because the armored cable serves no purpose beyond making the car difficult to steal, why can't you just run a new wire and ignore the armor completely? I also have a 1947 car so this would be good to know for future reference.

The issue on the switches with armored cable is the IGN terminal on the switch which supplies voltage only to the coil is behind the tiny hole for the armored cable crimp and is extremely hard to access. If you are not concerned about judging or anyone looking under the dash to see the change you could split the crimp holding the armored cable and just splice on a new wire as long as you didn't need to solder directly to the IGN terminal. As you can see, without undoing the edge crimps holding the back of the switch and other terminal support to the case the IGN terminal cannot be accessed. Make sure to protect the wire as it exits thru the small hole where the armor used to attach. The IGN terminal is an isolated terminal separately controlled by the switch and needs to be used to feed the coil to ensure the engine turns off when the key is off.

The 48 or 22nd series version of the switch could also be installed on the 47. It looks the same from the dash side but the switch has no armored cable and does have the IGN terminal fully accessible. It would be easy to run a short length of wire over to the coil terminal on the firewall. Using either switch and only a wire you could make a plate or reuse the original cap by removing the armored cable to cover the exposed coil terminal so it would look more finished to anyone looking under the dash. Protect the wire there too.

Thanks for the information. I don't have a show car so if I ever have that problem it will get a 48 switch.

Switch/cable in hand. length of cable, exclusive of switch and coil cap, that is to say armored cable only, is 21"
I also suspect this is used, not NOS, such that it has a lock cylinder in it. Nice used condition. I do not have the key for it...
fifty bucks?
