This is a brand new and unused rubber sealing grommet (guarnizione in gomma antenne, dichtung, tulle, bush, bezel, mount)  specifically for the Pininfarina designed Alfa Romeo 164 and 168 models manufactured between 1987 and 1998.  Over time if your grommet has become perished, lost, cracked, or become discoloured with over-spray or car wax, this will restore your aerial antenna's appearance. The grommet is angled at 14° (degrees from horizontal) and will push-fit into the original factory cut 22 mm circular hole in the rear wing/fender and securely seal and locate the ball-top type Zender and Hirschmann antennas that were factory fitted to these models.

If you require a complete replace electric aerial power antenna we can also supply suitable replacements.
