Ok, I guess I had one too many last night. Let me correct myself, doh. You will not have to remove the fender, not by any means. Where they fed the antenna wire, it will feed back through with no issue at all, is a fairly decent sized gap there. Even if you did remove the fender, you still would not have access. Chances are you can undo the existing base, and unplug the wire, easy stuff from there. Here are photos of a factory style antenna, and the holes where they feed. You'd have to make some holes, but is not hard to do at all. The trickiest part is getting the antenna cable fed through the inner fender and out the top hole on the fender, a coat hanger will help a lot though.

Help with the pictures: #1 is the antenna, plate on bottom, base in middle (wire and mast hook to this), cap. #2 is the factory hole area on the fender. #3 is the hole in the inner fender where the antenna wire is fed through, factory cable has a rubber grommet to seal up the hole. #4 is the hole in the firewall where it is fed through to the interior, also another rubber grommet on that. Hope any of this helps! Again there is no reason to remove your fender.
