Posting this on General forum since both pre- and postwar part. Where do you go for such grommets? Steele has the exact grommets with a superfluous lip, because on the 9/16" thick rod, under compression at that, it's not like they're going to shift. Not paying $70 for what are otherwise four (4) simple rubber grommets.
1 1/4 inches diameter, 9/16th inch hole, about 3/8" thick, but a minimum 1/4", judging by the below pictures. Mine under the car are obviously squished a little after 76 years of compression so hard to determine original thickness.
Section 5.1504, Packard part "insulator," # 348945
Here's a link picturing the snubber:
