I want to install better tweeters in my 2007 Mazda 3 (not bose). But the tweeters I want aren't the exact same physical dimensions as the old ones so they won't fit into the existing garnish. I've been searching for a place to order new "plain" inner garnishes so I can drill my own holes for the new tweeters but I can't find a web site that has them for a 2007. If anyone knows of a place where I can get these, please let me know.
