PSA: '65 Speedometer Grommet/Seal/Insulator (C6TZ-17261)

Public Service Announcement:
After searching far and wide I was unable to find what seemed like the right seal to use on my 65 Caliente for the the speedometer cable at the firewall. As far as I can tell there are no grommets available for the 65 Mustang (much less Comet/Falcon). There are grommets made for the 67+ Mustang but not, from what I have found, 1965.
I did however stumble on a the below product image for a 1965 Mustang Speedometer Cable assembly that is offered by Virginia Classic Mustang. You will note that a seal has been pre-installed.
For my '65 Caliente I have successfully installed (more or less) the speedometer firewall seal that suppliers have widely tagged for use with the 66-77 Bronco, and the 66-72 F-100/250/350, which is commonly listed as part C6TZ-17261 (such as here).
I suspect one of you know what was originally used at that location. I vaguely remember there being this kind of seal on my cable when I remoeved it ages ago (it was very deteriorated - crumbling apart as I pulled the cable). The Mercury and Ford (Falcon) Car Master Parts Catalogs do not list a part number entry for 17261.
FWIW the Bronco/Truck seal works nicely on my car and seems like a reasonable facsimile of the one used on the VCM assembly. I had to split it (like a hot dog bun) because I don't have the tools to remove/refit one of the terminals (which are too big to pass through the grommet on their own). But when installed that split is compressed back together quite firmly.
