Some FTO's came with Tweeters in the front underneath the cloth grills. If there are no tweeters there, you should have the factory plug just sitting there. I would recommend changing them if you do have them becuase they are not that good.
6x9 in the back..and I have 6.5" splits in the doors with the tweater mounted under the grille. easy mounting position. Be wary of the stock wiring...kinda crap - re-do all of it.
