Not offhand but except for a couple of 54 carbs without the accelerator start, the same 393937 ball is used across the range of those models listed in parts manual. Should be the same diameter on all Packards. If someone has an old carb apart that they could throw a micrometer on the ball, it might be something nice to know.

One thing I would wonder is why the vacuum is dropping so low and is there a possibility the air filter or screen at the bottom of the ball passage is blocked enough that there is not enough air flow for the vacuum to work with.
