OEM Whip Mod 2025
Friends and neighbors,
I did the thing. Went with parts from the dealer. $110 including shipping from WA to AK. The majority of the cost is the black whip antenna. I definitely have better reception now, and I'm hoping Toyota parts will work their magic and never break again.
"Antenna Assembly w/ hold" : 86300-35090
This is a 1999 Taco sub-assembly, no antenna included. You'll have to bend the bottom mounting bracket a little when you install.
"Pole sub-assembly, pull" : 86309-0C020
This is the black whip antenna from a 2005 FJ according to the dealer.
Buy some black plastic clips for the wheel well liner while you're at it.

Like everyone says, most of the work is running the cable to the back of the head unit.
When you unplug the old cable from the head unit, tie a long string to it before you remove it. Pop the old cable out of the two clips behind the center console air duct, and the two clips on either side behind the airbag. Then use your string to feed the new cable back into place. The job still sucks, but the string will help you.
This took me four hours to do, outside in the gravel, with my dusty corroded 4runner. Buy extra clips for the wheel well liner! Just do it.
I'm glad it's done... but I would rather pull the starter motor every day for the next week in stead of doing this ever again.
I found this video helpful, although he pulls the whole fender off, and there's no way in hell his flagging tape worked effectively like a string. Not possible. Still helpful.

Full Disclosure: I have a '97 Taco in my shed for parts, and if I didn't want the black whip antenna... and accidentally snipped the cable... I could have just pulled everything off that truck. Find one in a junk yard and do this for $5 I'll save my pennies and get rich in the next life.
