Adapter to fit a universal aerial to a Miata NC / MX5 Mk3 Top diameter of the adapter is 18mm The universal aerial is 17mm but the rubber squishes out slightly as it is tightened in The aerial I used for reference: https://www.ebay.co.uk/itm/153608849975 Only my second attempt so fitment could definitely be better but it's much better than nothing!
