I have looked at ALL the aftermarket folks with no luck..
The 78 power antenna setup was pretty unique..
The black plastic critter that fits thru the LR fender top is a guide ONLY for the antenna and was originally simply inserted from above and stayed in place with a couple of small 'ears'..Didn't attach to the antenna assembly below in any way.
You can possibly fabricate one using a rubber grommet such as fits in the top of the valve cover where the air hose inserts..
The hole needs to be sufficient diameter so the antenna TOP can be pushed thru it and the groove around the bottom wide enough to snap thru the fender and stay put.
Most auto stores have a wide selection of such grommets and they are commonly called PCV grommets.
Find one that has the top recessed down so the antenna when retracted has the end below the car's surface flush with the grommet top...
Measure hole in fender inside diameter and thickness of fiberglas fender top at the hole.
The grommet needs to be able to snap-fit into the hole in the fender.
Such a grommet like those for the Jeeps of older vintage are just about perfect.
If you are handy with files or a dremel, you could make one from a large rubber cork cut down, drilled and then the groove filed on the bottom..but a rubber PCV valve cover grommet selected properly and perhaps slightly modified would be simplest.
Top would be about 3/8" thick and flat with recess like the original was.. A slightly rounded top grommet would look fine..tho not original..
Careful work with a belt sander( grommet top on sander NOT sander on grommet top) will make it flat..
This is one of those small items that short of finding one on a junker vette 78 that had the power antenna and crawling underneath to remove it by pressing the little ears inward..you may never find..
Be creative..Jim
