Good afternoon...A couple of thoughts come to mind.
First, the threads are always just a tiny bid different on different manufacturers plugs. Might pay to get a nut the correct size and try it on some different plugs that will swap into your packard.

Second, ACE Hardware has a product called Pipe Thread Compound TFE Paste. It contains teflon in its mixture. It works on water, steam, natural and LP gas, oils, fuels and dilute acids. A little around the top three or so threads on the plug seems to do the trick...It would be a cheep fix. Ernie in Arizona
