Looking at the service manual those are 10mm plugs.

So from this post:https://packardinfo.com/xoops/html/modules/newbb/viewtopic.php?topic_id=24501&post_id=236196#forumpost236196

It says

AC MC-8
Autolite 3126
Champion UY-6

Maybe if those work for you, you could add a listing to the cross-reference on this site. My car has 14mm plugs so cannot directly check.
