I think the one pictured in Gary's post is the upper grommet for the support under the tank. As I understand it, Ford did not use a grommet in the firewall just one on the choke rod on the engine side of the firewall held in place by a metal cup washer and the spring. See part #14760 in Brattons catalog. If you want to use the non-original grommet supplied in the kit Brattons can probably give you the measurements.
