1957 license plate wire grommet?

[Bruce B.]

Per the 1957 Corvette AIM the grommets used on the body below the rear bumper are pn 3726434.
It appears that this item is not listed in the Corvette parts catalogs such as CC, Paragon, DocRebuild, etc.
What part is being used for this application? Just a generic square edge rubber grommet?
Thanks.

Bruce,
CC sells a 'firewall/body' grommet kit, their P/N301303. 9 pieces of the grommet used in most of the wire harness applications. Can't guarantee these are absolutely 'correct', but they look like it. I don't have my rear bumpers off, but they look to be the same size and have 1 small hole in the middle (for 1 wire). They're not much money - would probably be low risk getting them. CC has a good photo of them on their site.
I have used CC grommets in all the firewall and body applications, and they look to be identical to the original - including mfg. markings, and unlike most of the repop crap. -Dan-

When I installed the tag lamp grommets in my '57 the grommets were too large for the holes in the body. I wound up taking a razor blade and shaving small wedges in the grommet until it fit properly on the hole and looked correct. VIN 5899
