NOS switches are still available but at a cost. For some the work to replace a Packard switch with a universal may not be worth the effort but when you can pick up a universal switch for approx $20 and add a bit of work, for others it may be.

Problem I think you are goin to find is none of the universal or other mfg specific switches have pins in the spots that will attach to the Packard bezel and some have necks that are too large to slide inside the bezel or the dash. Most universals just want you to add a nut or threaded ring to hold them in place. If you want to do the quickest, easiest and cheapest without the bezel, then a universal switch with a 7/8 neck should fit the dash opening. I was able to find a universal switch with a threaded neck that would fit the bezel so I could keep the dash look intact but that was some time ago and don't have the switch information now. You need a switch with a 3/4" diameter threaded neck with the threaded portion being no more than 1/2" long.

On that switch I was able to remove the lock cylinder to drill and thread a couple of holes thru the neck in the pin locations. Then installed a couple of short setscrews to replace the pins. 4-40 and 6-32 x 3/16" long setscrews held by locktite will satisfactorily duplicate the two pin diameters and fit the bezel notches. You do need to be careful the screws do not extend down in the cylinder cavity and interfere with the rotation.

A minor issue is the universal switches will not have provisions for the key illumination bulb socket. You can carefully remove the socket and bracket assy from the old switch and use JB Weld or a hose clamp to attach it to the body of the new switch. Just be sure the socket maintains a good ground with whatever method is used to attach it and the hood lines up with the plastic light opening so the illumination can get thru the bezel when the switch is mounted.

You can reinstall the cylinder and leave it at that point and have a satisfactory replacement but it will require a third key. On the switch I found I was able to remove the cylinder and make a small adapter so the original Packard cylinder could fit and work the rest of the switch. That bit requires a bit of fine detail work and the cylinders need to be compatible. With so much being made overseas now maybe not a current option. Some other switches have a lock cylinder similar enough that the original key grooves will insert. On those, once the cylinder is out the key can be inserted and tumbler pins can be filed to fit and reworked so the Packard key can work the lock.

Pollack and some Cole Hersee universal switches are a couple I have found that will accept the Packard key in many cases. Since I used those on the 47 which needed a switch with a larger diameter neck don't have a number for one that will fit the 55-6 bezel or know for sure the Packard key will fit other model switches.
