Default Correct Name for Antenna Mounting Nut?



I hope the picture posts.
This is the nut/connector holding the antenna to the antenna outer body bezel on an 87. The thing is broken at the bottom where it supports the antenna.
I have no idea what the parts books call it. I'm afraid it's discontinued any way. I've looked at Corvette Central, Ecklers, Zip with no luck.
I'm guessing if I get one it will be part of a used antenna.
I'm starting to think about putting it back together to see if it really needs it.
Thanks for any advice.

Don't know the part name but they show up on Ebay from time to time. I think there's one listed now.

I know you have to use oem parts if you want to keep it flush...
90% of the aftermarket antenna kits use a mount thats has the grommet/seal sitting on top of the body panel instead of flush like the factory.

You can get an antenna bezel for about $18 and/or a replacement antenna mast with the mast nut for about $100. Check it out.

is this it ?



i think i have one of those things in a parts box - somewhere - ??? seems to me, and it's been many years since i've replaced the antenna on my 85, but as i recall, it has very coarse threads that screwed onto the antenna bezel and secured the power antenna to the body panel, and then, a lower bracket secured the antenna assembly to the frame. what do you call it - ??? - hell, i don't know - ??? try "corvette, 84-87, antenna, body outer bezel, lower antenna, panel mounting, UNC thread, underbody, ring retainer jam nut locking fastener" -
