1957 Oldsmobile Tail Light Grommet

1957 Oldsmobile rear light grommet. The wires for the rear tail lights go thru this grommet in the trunk. There is one grommet for each side (driver, passenger). The grommets are usually hard, cracked, or missing because of their age.

This should be printed with a rubber like material.

I created a mold and have been successfully casting the part: http://www.howmuchsnow.com/olds88/taillightplug/
