Vintage Truck fender antenna delete for CB antenna.

[Smokinone]

Looking for any ideas on mounting an antenna on a vintage truck in the original fender hole.
I was thinking possibly an original type antenna, if I can find one, with a match box...but only as a last effort. Just gonna be hooking up a Cobra 25 for more nostalgia, but function as well. My nephews truck and request.
Of course I'm going to have to recap the Cobra and make sure all is working. The radio has a sort of sentimental value him as he got it from passed friend.
Thanks.

Every mount I can remember to fit that size hole was discontinued decades ago. Hustler had one with a small swivel ball to compensate for the tilted mounting surface. Used a1/4 inch by 20 pitch thread for their stingers and for that mount, rather than the 3/8-24 that's become the standard since the 80s.

But looking under rocks to find an accessory to fit a truck that old is probably a familiar habit by now.

Thanks, I'll keep a look out.
Well, my nephew has a lot of ideas, and he usually passes them onto me for some kind of solution. We've pulled a few rabbits out of a hat to get him going. Maybe the old standby antenna...a coat hanger. But I don't think he has the base.
He wants to stay old school, maybe try and convince him a 102" whip is about as old school as you can get. In fact I still have the mount off my father in laws 64 wagon...won't fit in the hole though

During the CB craze of the 70's GM offered a AM/FM/CB radio with a motorized/power antenna option.

The antenna is for sale on ebay for a stupid price, but it is what you are looking for. Maybe you can find one at a better price. The GM part number is 22039302.

Here is the eBay link. https://www.ebay.com/itm/2671994361...pid=5336136228&customid=&toolid=10001&mkevt=1

From what I see, this doesn't have the integrated CB antenna.
I do appreciate your input though.
Also it's not complete. There's a Citizen brand on the bay that does have the CB antenna capability, but it is for a Corvette and is a flat type mount where the truck is angled.
Having had several of the motorized type antennas in the past, I don't think I would install another one.
I think I may have one of those antenna match or tuners by Paradynamics(?)
Something like this:

Maybe an SO mount antenna? What size is the hole?

I have an overly complicated idea. tape sandpaper to the fender over the mount hole and use it to shape the bottom of a block of styrofoam. Then, shape the rest to the shape you need for the mount. Pack it in sand and cast it out of brass (the brass will melt the foam and fill the void). Then, drill, tap, insert coil insulator, add 80" to 90" whip, then shunt feed it at a tap point.

Those little benchtop induction gold smelters are down to about $260 on amazon, almost low enough for a guy like me with a bucket of broken water valves to justify it. Almost.
