I believe he meant fender "liner". ;-)
I'll throw out my recent experience FWIW:
About a year ago the power antenna in my '02 Sport Edition croaked.
I spent $30 on a replacement mast and that worked fine for about two days and then it got eaten up (the white plastic gear whip thingy) so I pulled the fender liner and unplugged it.
Now, I don't like unfinished business but it was winter when this happened and I figured I'd fix it in the spring, which I just did a couple weeks back.
I found an "OEM Replacement" power assembly on Ebay for $69.99. Made specifically for the 2002 4Runner the ad said.
Bull. I get it and it some generic antenna that was 3" longer than the OEM and the power connectors totally different.
Okay. I'm good with electronics. After 2 hours of soldering and trying to make this generic POS fit, it ended up flying across my garage in a rare fit of frustration I usually don't exhibit.
The day after I ended up going to Toyota and getting the correct OEM replacement unit for $200.00 which is what I should have done in the first place.
The whole experience wasted about $100 (replacement mast that lasted a day and POS not-even-close-to-oem antenna).
The post above is correct, you'll need to get the replacement retainers for the fender liner (and in my case three rivets used on the fender flare because I took that off too).
Just my .02, but if you are _not_ going with the Tacoma whip and you _do_ want a power antenna, don't even waste your effort on the aftermarket crap you will find/waste money on. :bash:
