I want to replace the original tweeters in the door posts. Does anyone know what size tweeter will fit in that housing? Also, an easy to read and access wiring diagram and some step by step instructions on how to get those doors apart would be very helpfull. I know that this question has been asked before, but I'm hoping that someone will have some fresh info that doesn't lead to a site where the guy is asking for $4.99 for the info for the front door install and another $4.99 for the back.
