72 swinger taillight harness grommets

When mounting the rear bumper, I found one of the taillight harness grommets wouldn’t stay in place in the tail panel. Looking a bit closer at the grommet, I see the lip that holds it in place is torn off. The car is an hour away where it’s being assembled and I forgot to measure the hole or grommet before I left.

Wondering if anyone else has found a suitable replacement or can anyone measure the hole and tell me the size?
