On the left is the antenna I removed from my 85. It works fine except it is missing a grommet and there is a big gap that lets water in the trunk. The connector on it is also different (smaller diameter contacts on the 85) than the antenna from an 83 (on the right).
There does not appear to be any threads for a nut on the 85 antenna. Is the antenna on the left an OE correct antenna? Where can I buy just the grommet and what does it look like? I can't swap in the antenna on the right easily because of the connector difference.
