Installing component speakers on 2000 Accord EX

I wanted to try and install a Polk MOMO compnent system in my 2000 accord ex 4cyl, i found that the stock tweeters are located on the dash on either side of the windshield. Does anyone know how hard it would be to install the stock tweeters in this location, and what size the stock tweeters are. I would like to keep this install as stock looking as possible, which means no cutting of the dash or other parts that are visible. Any info on this subj is appreciated.

thanks,
Brian

The tweeters should be able to just pop out nicely... I dont see you having to take out the dash over it.
