Shark-fin antenna question
 

I stupidly hit my garage door with my antenna and broke it loose. There is some confusion about that entire assembly. The Toyota part number is SU003–05516 but I don't think that's what I need. The fin housing has a wire that attaches to a circuit board bolted to the roof from underneath and I think the circuit board is what I need. I can't find any blowups anywhere that show it, and my local Toyota dealer says none of those part numbers are available in the country. The antenna housing I have is still usable but has torn loose from the circuit board, and that's what I think I need. I can't find a part number or blowup anywhere for that board. Is anyone familiar with these?

Try a Pick-N-Pull.

There's no logical way to do that. The fin housing has a wire that attaches to a little plastic cap that covers the circuit board. The wire continues through the cap and must have been attached to the board but I can find no obvious point of connection. My only hope may be to find a fully-connected assembly on the used market.

No logical way??

Find a wrecked FRS/BRZ at a Pick-N-Pull (salvage yard, car-part.com, etc.). Remove the entire assembly and any other parts you think you might need/want. Swap the parts onto your car. Should be cheap.

Even cheaper. Find a FRS/BRZ and take apart their antenna to see where the wire is attached. If your board is still good the wire may be able to be reattached.

Source of confusion emboldened for emphasis.

The second Toyota dealer I talked to found the part I'm looking for in a local warehouse and I should have it in a day. I still don't know the part number. it's not in the blowup on the Toyota website.

Part # is SU003-02655

That's the amp for the original rubber ducky antenna.
