Fitting my antenna and saw that the black base is broken. You can see the space between the black base and the car. Does anyone have this black part for sale, know of a aftermarket part that would fit, or, a complete antenna? Thanks.......

 

An "old school" auto radio repair/installation shop would likely have a box somewhere filled with misc. antenna parts; they could most likely find you a fender seal that would fit. This part is actually separate from the slotted base which can be rotated to conform to the shape of your fender.

 

Ordered this one...looks like it will work. https://www.ebay.com/itm/Aerial-Ante...W/361608441895

Thanks everyone,

 

Devil Dog,
I think you will find that it is the rubber seal below the black ball that is broken. That may be all that you need.
