Power Mast Antenna - all different???
 

I have a dimple in my mast that stops it after 3/4 has dropped. On Ebay a new OEM mast runs about $30.00, but some for other Toyota models are $10 - $15 cheaper. Could Toyota have purchased so many different types of power antennas that a power mast antenna for a Camry is that much different than for a 4Runner?

Just wondering if I am being jerked around and the same mast works in lots of Toyota models.
