Bob;
If the 4-40 screws were Loctite'd I would think heat should be applied (per the advice on the 'LocTite' website) before they are removed . . . even if they are now broken. I bet a good sized soldering iron would do the trick.

Assuming you can find a shaft, you could drill and tap the throttle lever end and hold the Packard lever with a cup and screw . . . much like the other end of the shaft. Care must be taken while harvesting the donor shaft . . . as not to grind too much of the peened area.

I was trying to find which carburetors use the same lower flange, but my manual does not call-out the lower flange as a separate part. There is a listing for the flange assembly that includes the shafts and throttle valves. The assembly, of course includes the unique primary shaft & lever part, so that search was a dead-end. Perhaps Carter is trying to send a message that they would prefer the lower flange is managed as an assembly.

The manual associates the 2232 S with a '55 Clipper Super or Deluxe (5540), with head casting 440689 (likely jetted for a particular compression ratio), which should have 1 1/16 and 15/16 throttle valves. Are your throttle valves struck with a part number such as 2-92? Please confirm. My plan is to update my file for those carbs with 1 1/16 primary throttle valves. At least those carbs should have shafts with the same size 'flats' on the shaft. Please note the application is the 5540 chassis, not your Patrician 5580 chassis. I'm talking out of school on this subject in that I've never owned a 12 volt Packard.

I'll update the throttle shaft attachment, likely in a day or two. For what it's worth, all of the diagrams and photos I've looked at tend to indicate that the flats at the end of the shaft appear to be aligned with the throttle plate flats . . . meaning your Packard lever will likely be in the same 'o'clock' position with a band X shaft installed.
